http://httpd.apache.org/docs/2.2/mod/mod_cache.html#cachemaxexpire
I think the documentation is quite clear on this:
``Thus, documents will be out of date at most this number of seconds. This maximum value is enforced even if an expiry date was supplied with the document.''
If you remove the directive it will fall back to:
Default: CacheMaxExpire 86400 (one day)
What you probably want to do is invalidate the cache, but that can only be done with
htcacheclean from trunk so far: http://httpd.apache.org/docs/trunk/programs/htcacheclean.html
Which again only makes sense in a reverse proxy setup....
So long,

I know about Squid and tried that, but after many unsucessful attempts
configuring it and no time to research on Google, I decided to use
Apache.
Well, the caching is working well now without any problems.
