Hi Janine, The key with Apache documentation is to know which module is going to do what you want. Once you've figured that out, the docs are quite clear (with the exception of mod_rewrite of course :)
In this case I happen to know that the Cache-control header is generated by mod_expires, and you will find how to control it here: http://httpd.apache.org/docs/2.0/mod/mod_expires.html Your httpd config might have expiration set by default, or by file extension.
