Force browser to cache files

[GetFree]

I want to send the browser some headers to force it to cache .js and .css files.

Is there any way to configure apache to do this (using .htaccess)?

Thanks.

I would start with:

Mod_Expires [httpd.apache.org] AND Mod_Cache [httpd.apache.org] THEN Mod_Headers [httpd.apache.org]

This should give you some ideas.

Some hosts may not have the module(s) you need loaded, so you could have to implement a work-around.
EG I set the expires of my html pages with a php script, and use:

Header unset Cache-Control
Header set Cache-Control: "public,max-age=604800"

For all other files to be cached for one week.

Thank you Justin. That's just what I need.

I get a "Internal Server Error" message when I use the Header directive. I guess that means the module is not available.

Just one last question.

The Header directive will affect EVERY file in the directory where the htaccess file is located and all its sub-directories, right?

Standing alone, yes it will.

You can wrap it in a <Files> or <FilesMatch> container to make it conditional if needed.
