I’ve been through over 100 answers here, lots to try, NOTHING working??

Have a PHP based site. I need caching OFF for all .php files EXCEPT A SELECT FEW.

So, in .htaccess, I have the following:

ExpiresActive On
# Eliminate caching for certain dynamic files
<FilesMatch "\.(php|cgi|pl)$">
ExpiresDefault A0
Header set Cache-Control "no-cache, no-store, must-revalidate, max-age=0, proxy-revalidate, no-transform"
Header set Pragma "no-cache"
</FilesMatch>

Using Firebug, I see the following:

Cache-Control   no-cache, no-store, must-revalidate, max-age=0, proxy-revalidate, no-transform
Connection  Keep-Alive
Content-Type    text/html
Date    Sun, 02 Sep 2012 19:22:27 GMT
Expires Sun, 02 Sep 2012 19:22:27 GMT
Keep-Alive  timeout=3, max=100
Pragma  no-cache
Server  Apache
Transfer-Encoding   chunked
X-Powered-By    PHP/5.2.17

Hey, Looks great!

BUT, I have a couple .php pages I need some very short caching on.

I thought the simple answer was having this added to the very top of each php page in which I want caching enabled:

<?php header("Cache-Control: max-age=360"); ?>

Nope.

Then I tried various versions of the above. Nope.

Then I tried meta http-equiv variations. Nope.

Then I tried variations of the .htaccess code along with the above variations, such as limiting it to:

# Eliminate caching for certain dynamic files
<FilesMatch "\.(php|cgi|pl)$">
Header set Cache-Control "no-cache, max-age=0"
</FilesMatch>

Nope.

It seems nothing I do will allow a single .php to be cache enabled with the .htaccess code in place, short of removing the statements from the .htaccess file altogether.

Where am I going wrong? What do I have to do to get individual php pages to be cacheable while the rest remain off??

Thank you for any thoughts.

    Well, apparently this has no answer. So, my solution at this point is to eliminate the .htaccess code altogether, and apply explicit headers to each file. A pain in the you-know-what but it’s time to move on. If anyone has a more elegant solution that can work with an .htaccess default please feel free to share… thanks
