gzip compression

[cornnfedd]

I tried to use gzip but got an error, is this set up for glowhost?


quote from phpmotion below.

This is probably the easiest, quickest thing you can do to speed up your site.
Open your main .htaccess file (ie the one in your public_html), and add this into it.

php_flag zlib.output_compression on
php_value zlib.output_compression_level 1
ErrorDocument 404 /404.php
AddOutputFilterByType DEFLATE text/css application/x-javascript
AddOutputFilterByType DEFLATE text/css application/x-javascripts

This compresses every file on your site (including that heavy javascript and CSS) by as much as 70% and makes it much faster to load.
Also thrown in there for free is the correct 404 code which is also missing from the default install.
This requires some common modules to be installed on your server, and some cheaper hosts will not have these installed as it increases the load on the server a little, meaning they cant cram as many sites onto the server. If you get a problem after installing it, theres nothing you can do but remove the code again.

As this is used by some common mods on this site, if you have no mods it wont harm to leave it there.

I think when he says "cheaper" he means "shared."

On a shared host the speed gained is minimal compared to the load that is added by enabling this module. I wouldn't be surprised if the sites loaded slower in general on a gzip enabled shared server.

It is not enabled for performance reasons on shared hosts but can be enabled on VPS and dedicated if you like.
