CodingForums.com - Are files automatically GZIP'd?

Hi

I found some htaccess code today that GZIPs your files.

Code:

<IfModule mod_gzip.c>

        mod_gzip_on                        Yes

        mod_gzip_dechunk        Yes

        mod_gzip_item_include file                        \.(html?|txt|css|js|php|pl)$

        mod_gzip_item_include handler                ^cgi-script$

        mod_gzip_item_include mime                ^text\.*

        mod_gzip_item_include mime                ^application/x-javascript.*

        mod_gzip_item_exclude mime                ^image\.*

        mod_gzip_item_exclude rspheader        ^Content-Encoding:.*gzip.*

</IfModule>

I thought that Apache automatically did this? Or do you have to turn this on?

Would you recommmend turning this on?
