Best way to enable html/text compression via mod_deflate

[Jagbir Singh]

Hi,

we have around 60 sites running in plesk on CentOS 5.2 server. We would like to implement html/text compression by putting following statements in apache config file:

"
AddOutputFilterByType DEFLATE text/xml
AddOutputFilterByType DEFLATE text/css
AddOutputFilterByType DEFLATE application/x-javascript
AddOutputFilterByType DEFLATE text/html
"

want to ask, where should I put this info to make it global for all existing sites and any new site that might be added in future?

Thanks & Regards,
Jagbir Singh
