Use the Dispatcher Release Notes page to obtain the latest Dispatcher installation file for your operating system and web server. Dispatcher release numbers are independent of the Adobe Experience Manager release numbers and are compatible with Adobe Experience Manager 6.x, 5.x and Adobe CQ 5.x releases.

NOTE

Adobe Experience Manager 6.5 requires Dispatcher version 4.3.2 or higher. That said, Dispatcher versions are independent of AEM, for example, Dispatcher version 4.3.2 is also compatible with Adobe Experience Manager 6.4.

The following file naming convention is used:

dispatcher-<web-server>-<operating-system>-<dispatcher-version-number>.<file-format>

For example, the dispatcher-apache2.4-linux-x86_64-ssl-4.3.1.tar.gz file contains Dispatcher version 4.3.1 for an Apache 2.4 web server that runs on Linux® i686 and is packaged using the tar format.

The following table lists the web server identifier that is used in file names for each web server:

Web Server

Installation Kit

Apache 2.4

dispatcher-apache 2.4-<other parameters>

Microsoft® Internet Information Server 7.5, 8, 8.5, 10

dispatcher-iis-<other parameters>

Sun Java™ Web Server iPlanet

dispatcher-ns-<other parameters>

CAUTION

Be sure you install the latest version of Dispatcher that is available for your platform. On a yearly basis, upgrade your Dispatcher instance to use the latest version to take advantage of product improvements.

NOTE

Customers upgrading specifically from version 4.3.3 to version 4.3.4 should notice a different behavior in how caching headers are set for uncacheable content. To read more about this change, see the Release Notes page.

Each archive contains the following files:

the Dispatcher modules
an example configuration file
the README file that contains installation instructions and last-minute information
the CHANGES file that lists issues fixed in current and past releases

Configuring Microsoft® IIS configuring-microsoft-iis

Configure IIS to integrate the Dispatcher ISAPI module. In IIS, you use wildcard application mapping.

Configuring Anonymous Access - IIS 8.5 and 10 configuring-anonymous-access-iis-and

The default Flush replication agent on the Author instance is configured so that it does not send security credentials with flush requests. Therefore, the website on which that you are using the Dispatcher cache must allow anonymous access.

If your website uses an authentication method, the Flush replication agent must be configured accordingly.

Open IIS Manager and select the website that you are using as the Dispatcher cache.
Using Features View mode, in the IIS section double-click Authentication.
If Anonymous Authentication is not enabled, select Anonymous Authentication and in the Actions area click Enable.

Integrating the Dispatcher ISAPI Module - IIS 8.5 and 10 integrating-the-dispatcher-isapi-module-iis-and

Use the following procedure to add the Dispatcher ISAPI module to IIS.

Open IIS Manager.
Select the website that you are using as the Dispatcher Cache.
Using Features View mode, in the IIS section double-click Handler Mappings.
In the Actions panel of the Handler Mappings page, click Add Wildcard Script Map, add the following property values, and then click OK:
- Request Path: *
- Executable: The absolute path of the disp_iis.dll file, for example C:\inetpub\Scripts\disp_iis.dll.
- Name: A descriptive name for the handler mapping, for example Dispatcher.
In the dialog box that appears, to add the disp_iis.dll library to the ISAPI and CGI Restrictions list, click Yes.

For IIS 7.0 and 7.5, the configuration is complete. Continue with the remaining steps if you are configuring IIS 8.0.
(IIS 8.0) In the list of Handler Mappings, select the one that you created, and in the Actions area click Edit.
(IIS 8.0) In the Edit Script Map dialog box, click the Request Restrictions button.
(IIS 8.0) To ensure that the handler is used for files and folders that are not yet cached, deselect Invoke Handler Only If Request Is Mapped To. Click OK.
(IIS 8.0) On the Edit Script Map dialog box, click OK.

Configuring Access to the Cache - IIS 8.5 and 10 configuring-access-to-the-cache-iis-and

Provide the default App Pool user with write-access to the folder that is being used as the Dispatcher cache.

Right-click the root folder of the website that you are using as the Dispatcher cache and click Properties, such as C:\inetpub\wwwroot.
On the Security tab, click Edit, and then in the Permissions dialog box, click Add. A dialog box opens for selecting user accounts. Click the Locations button, select your computer name, and then click OK.

Keep this dialog box open while you complete the next step.
in IIS Manager, select the IIS site that you are using for the Dispatcher cache, and on the right side of the window, click Advanced Settings.

Apache Web Server apache-web-server

CAUTION

Instructions for installation under both Windows and UNIX® are covered here. Be careful when performing the steps.

Installing Apache Web Server installing-apache-web-server

For Information about how to install an Apache Web Server read the installation manual - either online or in the distribution.

CAUTION

If you are creating an Apache binary by compiling the source files, make sure that you turn on dynamic modules support. Enabling this option can be done using any of the –enable-shared options. At a minimum, include the mod_so module.

More information can be found in the Apache Web Server installation manual.

Also see the Apache HTTP Server Security Tips and Security Reports.

Apache Web Server - Add the Dispatcher Module apache-web-server-add-the-dispatcher-module

The Dispatcher comes as either:

Windows: a Dynamic Link Library (DLL)
UNIX®: a Dynamic Shared Object (DSO)

The installation archive files contain the following files - dependent on whether you have selected Windows or UNIX®:

File

Description

disp_apache<x.y>.dll

Windows: The Dispatcher dynamic link library file.

dispatcher-apache<x.y>-<rel-nr>.so

UNIX®: The Dispatcher shared object library file.

mod_dispatcher.so

UNIX®: An example link.

http.conf.disp<x>

An example configuration file for the Apache server.

dispatcher.any

An example configuration file for the Dispatcher.

README

Readme file that contains installation instructions and last-minute information. Note: Check this file before starting the installation.

CHANGES

Changes a file that lists issues fixed in the current and past releases.

Use the following steps to add the Dispatcher to your Apache Web Server:

Place the Dispatcher file in the appropriate Apache module directory:
- Windows: Place disp_apache<x.y>.dll <APACHE_ROOT>/modules
- UNIX®: Locate either the <APACHE_ROOT>/libexec or <APACHE_ROOT>/modulesdirectory according to your installation.
  Copy dispatcher-apache<options>.so into this directory.
  To simplify long-term maintenance, you can also create a symbolic link named mod_dispatcher.so to the Dispatcher:
  ln -s dispatcher-apache<x>-<os>-<rel-nr>.so mod_dispatcher.so
Copy the dispatcher.any file to the <APACHE_ROOT>/conf directory.

Note: You can place this file in a different location, as long as the DispatcherLog property of the Dispatcher module is configured accordingly. (See Dispatcher-Specific Configuration Entries below.)

Apache Web Server - Configure SELinux Properties apache-web-server-configure-selinux-properties

If you are running Dispatcher on Red Hat® Linux® Kernel 2.6 with SELinux enabled, you might run into error messages like this in the Dispatcher logfile.

Mon Jun 30 00:03:59 2013] [E] [16561(139642697451488)] Unable to connect to backend rend01 (10.122.213.248:4502): Permission denied

This error is likely due to an enabled SELinux security. If so, perform the following tasks:

Configure the SELinux context of the Dispatcher module file.
Enable HTTPD scripts and modules to make network connections.
Configure the SELinux context of the docroot, where the cached files are stored.

Enter the following commands in a terminal window, replacing [path to the dispatcher.so file] with the path to the Dispatcher module that you installed to Apache Web Server, and path to the docroot with the path where the docroot is located (for example, /opt/cq/cache):


semanage fcontext -a -t httpd_modules_t [path to the dispatcher.so file]
setsebool -P httpd_can_network_connect on
chcon -R --type httpd_sys_rw_content_t [path to the docroot]
semanage fcontext -a -t httpd_sys_rw_content_t "[path to the docroot](/.*)?"

Apache Web Server - Configure Apache Web Server for Dispatcher apache-web-server-configure-apache-web-server-for-dispatcher

The Apache Web Server must be configured, using httpd.conf. In the Dispatcher installation kit, find an example configuration file named httpd.conf.disp<x>.

These steps are compulsory:

Navigate to <APACHE_ROOT>/conf.
Open httpd.conffor editing.
The following configuration entries must be added, in the order listed:
- LoadModule to load the module on startup.
- Dispatcher-specific configuration entries, including DispatcherConfig, DispatcherLog, and DispatcherLogLevel.
- SetHandler to activate the Dispatcher. LoadModule.
- ModMimeUsePathInfo to configure the behavior of mod_mime.

(Optional) It is recommended that you change the owner of the htdocs directory:

The Apache server starts as root, though the child processes start as daemon (for security purposes). The DocumentRoot (<APACHE_ROOT>/htdocs) must belong to the user daemon:

code language-xml
`cd <APACHE_ROOT> chown -R daemon:daemon htdocs`

LoadModule

The following table lists examples that can be used; the exact entries are according to your specific Apache Web Server:

Windows

... LoadModule dispatcher_module modules\disp_apache.dll ...

UNIX® (assuming symbolic link)

... LoadModule dispatcher_module libexec/mod_dispatcher.so ...

NOTE

The first parameter of each statement must be written exactly as in the above examples.

See the example configuration files provided and the Apache Web Server documentation for full details about this command.

Dispatcher specific configuration entries

The Dispatcher-specific configuration entries are placed after the LoadModule entry. The following table lists an example configuration that is applicable for both UNIX® and Windows:

Windows & UNIX®

...
<IfModule disp_apache2.c>
DispatcherConfig conf/dispatcher.any
DispatcherLog logs/dispatcher.log DispatcherLogLevel 3
DispatcherNoServerHeader 0 DispatcherDeclineRoot 0
DispatcherUseProcessedURL 0
DispatcherPassError 0
DispatcherKeepAliveTimeout 60
</IfModule>
...

NOTE

The individual configuration parameters:

Parameter

Description

DispatcherConfig

Location and name of the Dispatcher configuration file.
When this property is in the main server configuration, all virtual hosts inherit the property value. However, virtual hosts can include a DispatcherConfig property to override the main server configuration.

DispatcherLog

Location and name of the log file.

DispatcherLogLevel

Log level for the log file:
0 - Errors
1 - Warnings
2 - Infos
3 - Debug
Note: Set the log level to 3 during installation and testing, then to 0 when running in a production environment.

DispatcherNoServerHeader

This parameter is deprecated and ineffective.

Defines the Server Header to be used:

undefined or 0 - The HTTP server header contains the AEM version.
1 - The Apache server header is used.

DispatcherDeclineRoot

Defines whether to decline requests to the root “/”:
0 - accept requests to /
1 - The Dispatcher does not handle requests to /. Instead, use mod_alias for the correct mapping.

DispatcherUseProcessedURL

Defines whether to use pre-processed URLs for all further processing by Dispatcher:
0 - use the original URL passed to the web server.
1 - the Dispatcher uses the URL already processed by the handlers that precede the Dispatcher (that is, mod_rewrite) instead of the original URL passed to the web server. For example, either the original or the processed URL is matched with Dispatcher filters. The URL is also used as the basis for the cache file structure. See the Apache website documentation for information about mod_rewrite; for example, Apache 2.4. When using mod_rewrite, use the flag ‘passthrough’ (pass through to the next handler) to force the rewrite engine to set the URI field of the internal request_rec structure to the value of the filename field.

DispatcherPassError

Defines how to support error codes for ErrorDocument handling:
0 - Dispatcher spools all error responses to the client.
1 - Dispatcher does not spool an error response to the client (where the status code is greater or equal than 400). Instead, it passes the status code to Apache, which allows an ErrorDocument directive to process such a status code.
Code Range - Specify a range of error codes for which the response is passed to Apache. Other error codes are passed to the client. For example, the following configuration passes responses for error 412 to the client, and all other errors are passed to Apache: DispatcherPassError 400-411,413-417

DispatcherKeepAliveTimeout

Specifies the keep-alive timeout, in seconds. Starting with Dispatcher version 4.2.0 the default keep-alive value is 60. A value of 0 disables keep-alive.

DispatcherNoCanonURL

Setting this parameter to On passes the raw URL to the backend instead of the canonicalized one and overrides the settings of DispatcherUseProcessedURL. The default value is Off.
Note: The filter rules in the Dispatcher configuration are always evaluated against the sanitized URL not the raw URL.

NOTE

Path entries are relative to the root directory of the Apache Web Server.

NOTE

The default settings for the Server Header are:

ServerTokens Full

DispatcherNoServerHeader 0

Which shows the AEM version, for statistical purposes. If you want to disable such information being available in the header, you can set the following:

ServerTokens Prod

See the Apache Documentation about ServerTokens Directive (for example, for Apache 2.4) for more information.

SetHandler

After these entries you must add a SetHandler statement to the context of your configuration ( <Directory>, <Location>) for the Dispatcher to handle the incoming requests. The following example configures the Dispatcher to handle requests for the complete website:

Windows and UNIX®

...
<Directory />
<IfModule disp_apache2.c>
SetHandler dispatcher-handler
</IfModule>

Options FollowSymLinks
AllowOverride None
</Directory>
...

The following example configures the Dispatcher to handle requests for a virtual domain:

Windows

...
<VirtualHost 123.45.67.89>
ServerName www.mycompany.com
DocumentRoot _\[cache-path\]_\\docs
<Directory _\[cache-path\]_\\docs>
<IfModule disp_apache2.c>
SetHandler dispatcher-handler
</IfModule>
AllowOverride None
</Directory>
</VirtualHost>
...

UNIX®

...
<VirtualHost 123.45.67.89>
ServerName www.mycompany.com
DocumentRoot /usr/apachecache/docs
<Directory /usr/apachecache/docs>
<IfModule disp_apache2.c>
SetHandler dispatcher-handler
</IfModule>
AllowOverride None
</Directory>
</VirtualHost>
...

NOTE

The parameter of the SetHandler statement must be written exactly the same as the above examples because it is the name of the handler defined in the module.

See the example configuration files provided and the Apache Web Server documentation for full details about this command.

ModMimeUsePathInfo

After the SetHandler statement, you should also add the ModMimeUsePathInfo definition.

NOTE

Only use and configure the ModMimeUsePathInfo parameter if you are using Dispatcher version 4.0.9, or higher.

Dispatcher version 4.0.9 has been released in 2011. If you are using an older version, upgrading to a recent Dispatcher version is appropriate.

The ModMimeUsePathInfo parameter should be set On for all Apache configurations:

ModMimeUsePathInfo On

The mod_mime module (for example, Apache Module mod_mime) is used to assign content metadata to the content selected for an HTTP response. The default setup means that mod_mime determines the content type. As such, only the part of the URL that maps to a file or directory is considered.

When On, the ModMimeUsePathInfo parameter specifies that mod_mime is to determine the content type based on the complete URL; this means that virtual resources have metainformation applied based on their extension.

The following example activates ModMimeUsePathInfo:

Windows and UNIX®

...
<Directory />
<IfModule disp_apache2.c>
SetHandler dispatcher-handler
ModMimeUsePathInfo On
</IfModule>

Options FollowSymLinks
AllowOverride None
</Directory>
...

Enable Support for HTTPS (UNIX® and Linux®) enable-support-for-https-unix-and-linux

Dispatcher uses OpenSSL to implement secure communication over HTTP. Starting from Dispatcher version 4.2.0, OpenSSL 1.0.0 and OpenSSL 1.0.1 are supported. Dispatcher uses OpenSSL 1.0.0 by default. To use OpenSSL 1.0.1, use the following procedure to create symbolic links so that the Dispatcher uses the OpenSSL libraries that are installed.

Open a terminal and change the current directory to the directory where the OpenSSL libraries are installed, for example:

code language-shell
`cd /usr/lib64`

To create the symbolic links, enter the following commands:

code language-shell
`ln -s libssl.so libssl.so.1.0.1 ln -s libcrypto.so libcrypto.so.1.0.1`

NOTE

If you are using a customized version of Apache, make sure Apache and Dispatcher are compiled using the same version of OpenSSL.
