Which mod_pagespeed functions do you support?

Our Linux-based Web Hosting accounts can use mod_pagespeed, which is an open-source module that optimizes Web pages and their resources for better performance. For more information, see Google's documentation.

You can enable it on your hosting account through a .htaccess file. Here's an example of the coding you can include in your .htaccess file to enable the Extend Cache function:

<IfModule pagespeed_module>
   ModPagespeed on
   ModPagespeedEnableFilters extend_cache
</IfModule>

You can enable the following functions using the ModPagespeedEnableFilters directive:

Function	pagespeed.conf Code
Extend Cache	extend_cache
Collapse Whitespace	collapse_whitespace
Combine CSS	combine_css
Move CSS to HEAD	move_css_to_head
Elide Attributes	elide_attributes
Remove Comments	remove_comments

Other Features of mod_pagespeed

You can also enable the following directives in the .htaccess file:

• ModPagespeedDisallow

For more information about using these directives, see Using mod_pagespeed.

We are still testing any mod_pagespeed functions not yet listed for compatibility, performance, and reliability. Because mod_pagespeed is still in a beta offering, its features might change. We also cannot guarantee that any enabled modules will not conflict with your website's existing content.
