UseLastModified uselastmodified
Enable last-modified response headers. Enables or disables inclusion of the Last-Modified header in cacheable HTTP responses emitted by Image Rendering.
The server uses the most recent vignette::TimeStamp
and catalog::TimeStamp
value of all vignette and material catalogs/catalog records involved in a response as the Last-Modified header value.
Should be enabled only if a distributed caching network, such as Akamai, is used which does not support etag headers.
-
catalog::TimeStamp
,vignette::TimeStamp
, orattribute::TimeStamp
is not defined, so that the modification time of the catalog.ini file is used as the default forcatalog::TimeStamp
. -
Instead of sharing the material catalog files by way of a network mount, each server has its own instance of the catalog files on a local file system.
-
Two or more instances of the same catalog.ini file have different file modification dates, possibly caused by improper copying of the files.
