Topic: Problem with apache headers

[sawyoh]

Hi,

I am trying to setup dynamic content configuration in apache 2.2 httpd conf. Here is the configuration and couple test cases:

CONF:
<FilesMatch "\.(js|css|gif|jpg|jpeg|png)$">
Header set Cache-Control "no-cache, no-store, max-age=0, must-revalidate"
</FilesMatch>

TEST 1:
Without <FilesMatch> directive, the headers are set to all requested content as it should. This includes content served from apache server and content from a separate application server.

TEST 2:
If I use the above configuration example, I can see that static content comes with correct headers only when the content is served from apache (mainpage and some pictures are handled by apache). However, all other static content in applications that reside in a separate application server no longer have the header information.

I have not been able to find a relevant article other than basic guides to Apache Headers but these don't take a separate application server into an account (though, I guess they should not as the requests and responses are tunneled through apache).

What could be the issue? is the FilesMatch only working with content served from apache? Should I use another directive to capture the static content that is served from my application server? Could this be a regex issue or maybe something to do with folder/file permissions?

Here is an example of headers captured with Fiddler. In this scenario (TEST 2), the picture "player_fi.jpg" does not have any header information.
