[users@httpd] Conditional disabling of caching (mod_cache) based on presence of certain cookie possible ?

[Soumendu Bhattacharya <so...@non.agilent.com>]

Hi,

        We use Apache + mod_cache for caching our website. Our mod_cache
rule is such that it enables caching for all and then selectively certain
url pattern is disabled (like some contexts). Currently the need is that if
a certain cookie is present , the same url which was originally cached ,
should now be prevented from caching. Say I was caching xyz.com/a/b.html ,
but now if a certain cookie say NO-CACHE is present , the same
xyz.com/a/b.html should not be served from cache. The url's which can
contain NO-CACHE cookie is not limited (cannot be defined fully) and hence
it looks like I need to check the presence of this cookie and then figure
out a way to prevent (if the cookie is present) Apache from serving the
content from cache.

 

Any help will be greatly appreciated 

 

Thanks in advance 

 

Regards

 

Soumendu

Why a cookie? There's Cache-Control: HTTP header designed for this, not 
Cookie:
