Here's what I do for my site (it's not accessible to public right now):

• Open index.php
• Scroll down until you see the header("Content-Type") line
• Below that line add this: header("Content-Length: ".strlen($html));
• Then add this line: header("Cache-Control: public, max-age=60, s-maxage=60");

For more info about those lines read Caching Tutorial for webmasters and web authors: http://www.mnot.net/cache_docs/

Hello,

Thank you.
I'm pretty sure this is what Apache's mod_cache is doing without touching CMSms' code.
But not all hosting providers provide mod_cache which they should love.

Though the content length mod should be harmless, the caching header should only be done if the page is marked as cachable..  dynamic pages (like those with content from FEU or CustomContent, etc), should not cache.

Hi!

Depending on the nature of your site, you might cache various elements via .htaccess file.

Here's what I use:



This is from a site which barely changes.

hth,
Alex

Hi Alex,

thanks for that (for me unknown) hints - will adding this to tuning guide .

Hi Andreas,

don't forget to add this link:
http://www.ircache.net/cgi-bin/cacheability.py

With this "cacheability engine"  you can check how the elements of your page are cached - nice for nailing down specific cache conditions.

Additionally I can recommend the "live http headers" extension for Firefox:
http://addons.mozilla.org/firefox/addon/3829

And as taufkip already mentioned, you have to understand
http://www.mnot.net/cache_docs/
first or you'll get in trouble.


Cheers,
Alex

Thank you Alex.
Andreas, where is the tuning guide ?
Have fun

Pierre M.

(made this topic sticky)

Hmm, have tried it from a vserver, but got only a 500 error from server ...

What's wrong?

What is in the logs ?

Do you have mod_expires installed?

Alex

Thx Alex (and Pierre).

I see I must have tomatos on my eyes - mod_expires was not installed (I've afraid it) .

Great document - I see, I have a lot to translate ...

Yes, great. I like very much what is said about URLs, configs... And even already translated in French and Czech
Please notice : this march version is focused on browser side cache tuning (via mod_expires and mod_headers). May be the next will add mod_cache about webserver cache tuning in front of a "dynamic" content like CMSms (and obviously all expires and headers recommandations remain efficient).
