[users@httpd] "Expires" and "Cache-Control" don't work properly

[Diana Horvitz <Di...@exlibris.co.il>]

Hi,

 

I have a system in which all the pages are generated on the fly.

I want those pages not to be cached. I do want to cache images and css
files.

 

I have two servers, with two different configuration directives

Server 1)

Header set Pragma "no-cache"

Header set Expires "Fri, 01 Jan 2000 00:00:00 GMT"

Header set Cache-Control "no-cache, must-revalidate"

 

ExpiresActive on

ExpiresDefault "now"


ExpiresByType image/gif A2592000

ExpiresByType image/jpeg A2592000

ExpiresByType image/jpg A2592000


ExpiresByType text/css  A2592000

 

Server 2)

Header set Pragma "no-cache"

Header set Expires "Fri, 01 Jan 2000 00:00:00 GMT"

Header set Cache-Control "no-cache, must-revalidate"

 

ExpiresActive on

ExpiresByType image/gif A2592000

ExpiresByType image/jpeg A2592000

ExpiresByType text/css  A2592000

 

<Files ~ "\.(gif|jpe?g|png|css|sav)$">

    Header unset Cache-Control

    Header unset Expires

    Header unset Pragma

</Files>

 

The problem I have (on both servers) is that the pages ARE cached, no matter
the definitions of Expires and Headers.

We have Apache 2.0.52 installed on both servers.

 

What am I doing wrong?

 

Thanks in advance,

 

Diana.
