Both responses look cachable. Not sure why mod_cache wouldn't be
caching them...

NO. mod_file_cache simply mmaps static files' filehandles, enabling
Apache to serve them much faster. The name is really misl
Correct. You'll start seeing subdirectories under you cacheroot
immediately. You can also try turning up the log level to LogLevel
debug and looking at the error_log for more hints.

I tried to use apache 2.2.4. Then mod_cache could catch the reponses. So
I do not need to develop a filter for this function. :-)
Thanks a lot for your help.

David,
1) I tried /gethint.php without any GET/POST parameters. I got nothing
and it could not be cached even with force-caching directive. I do the
same thing for clienthint.js. It could work and display the source code
and could be cached.

Erica,
My only comments: either
(1) the request parameters are killing mod_cache's desire to cache the file
or
(2) something is different in the headers between your JavaScript and PHP
responses.

Yes. I changed the PHP script. Now I change them back and also set

Yes, see http://httpd.apach
Erica,
My observations of your headers:

David,
I printed out the response header, by use of
xmlHttp.getAllResponseHeaders(), which could get the whole headers of
the response. So through it, I could know that the headers have been
added successfully to the responses.
For mod_cache, I just use mod_disk_cache instead of mod_mem_cache
Erica,
I would follow Joachim's recommendation to:
You may want to use Firefox with the LiveHttpHeaders Plugin to look at
the headers, that are actually exchanged (or are you already doing
that).
My coworker informs me that PHP automatically updates the "last updated"

AFAIK, there's no reason that mod_cache shouldn't be able to cache your
output, as long as the request is a GET and not POST, and not otherwise
uncachable (eg, not authenticated, cache headers are present, expires in
future, etc). It runs as an output filter, so the fact that the

IIRC, JavaScript is used on the presentation request (with the webpage),
whereas the XMLHttpRequest response is a PHP-generated XML document.

Well, my question is not on the usage of mod_cache. In fact, I have used
local applications to add caching headers and configure mod_cache to
catch those HTTP responses. However I could not catch those HTTP

IMO, your caching should take place on the PHP side of things, not Apache

Depending on how frequently the cache should refresh, I would either have
