chaching and php

[Anon]

i am planning my site to run on httpd accleration caching.
Most of my pages are dynamic which come from the database. I am using apache as the webserver and php for db connectivity and scripting.
For caching apache should send out proper headers and expires and cache-control directives. I have recompiled my apache withe the following options

./configure --prefix=/usr/local/apache2 --enable-module=rewrite --enable-
shared=rewrite --enable-module=src/modules/php4/libphp4.a --enable-module=src/mo
dules/standard/mod_headers --enable-module=src/modules/standard/mod_expires

and install the apache
but when i do httpd -l it does not show me the mod_headers.c and mod_expires.c modules.
please help

also are there any other issues regarding caching which i should look out for.

please help
Thank you.

If you are using dynamic pages, what's the point of caching?

Hi,

We want to cache as the pages have to call the database every time which ultimately slows down the site. So if the sql querys is returning the same data again and again(it happens for 30 mins) we want to cache the page for 30 mins.

I see.

But it means that when you request the page, then update the database,
the updates will not be visible for 30 minutes, the users wil allways be lagging 30 minutes.

If you can live with that it's ok :-)

Hi,

Yes we can live with it. As we are not going to update the database for 30 mins.
