.htaccess setting for more caching?

[blakekr]

I realize this is a really vague question, but is there something I can put in my .htaccess to enable more caching for my static pages? Since I've moved a data-heavy site over here, it seems like it's reloading from scratch everytime I pull up a page.

i dont think so. if its php there is some sort of "program" called php cache, google for it.

The server does not do any sort of HTTP, PHP, or MySQL caching. Only such a setting would exist in your browser.

Are your static pages extension .HTML? PHP files, of course, load the PHP engine (or at least initialize the environment) and therefore are slower even if they are only static HTML. Just my 2 cents.

Here's a good Sitepoint article about Caching with PHP/MySQL

Gzipping is not caching, but it can help performance. I put these lines in my php.ini file:

zlib.output_compression = ON;
zlib.output_compression_level = 1;

There is a way indeed to send cache-related http headers to the client. This is what I use for static images and stuff that doesn't change often: just add text/html for your web pages to be cached (client-side). Values are in seconds from last access; look the Apache docs for more options (http://httpd.apache.org/docs/1.3/mod/mod_expires.html)
