Log Format
The log entries produced by proxy-2.1.jar all have the following format:
[timestamp (optional)] [Client|Server]-[ConnectionNumber]-[BytePosition] ->[Character Stream]
For example, a request for a Web page may look as follows:
C-0-#000000 -> [GET /author/prox.html?CFC_cK=1102938422341 HTTP/1.1 ]
- C signifies that this entry comes from the client (it is a request for a Web page)
- 0 is the connection number (the connection counter starts at 0)
- #00000 the offset in the byte stream. This is the first entry, so the offset is 0.
[GET <?>]is the content of the request, in the example one of the HTTP headers (url).
When a connection closes, the following information is logged:
C-6-Finished: 758 bytes (1.0 kb/s)
S-6-Finished: 665 bytes (1.0 kb/s)
This shows the number of bytes that passed between client ( C) and the server ( S) on the sixth connection and at the average speed.
An Example of Log Output
As an example, consider a page that produces the following code when requested:
Example
As an example, consider a simple html document in the repository at
/content/test.html
Alongside an image file at
/content/test.jpg
The content of test.html is:
<html>
<head>
<title>Test</title>
</head>
<body>
Test<br>
<img src="test.jpg">
</body>
</html>
Assuming the AEM instance is running on localhost:4502, the proxy is started like this:
java -jar proxy.jar localhost 4502 4444 -logfile test.log
The CQ/CRX instance can now be accessed though the proxy at localhost:4444 and all communication by way of this port is logged to test.log.
If you now watch the output of the proxy, you see the interaction between the browser and the AEM instance.
On startup, the proxy outputs the following:
starting proxy for localhost:4502 on port 4444
using logfile: <some-dir>/crx-quickstart/opt/helpers/test.log
Now open a browser and access the test page:
http://localhost:4444/content/test.html
And you see that the browser makes a GET request for the page:
C-0-#000000 -> [GET /content/test.html HTTP/1.1 ]
C-0-#000033 -> [Host: localhost:4444 ]
C-0-#000055 -> [Connection: keep-alive ]
