Assuming this is a follow-on from your work on caching youtube, You want the url_rewrite_program option. It's more of an API for external scripts than a native filter. An internal one has long been on the wishlist of one-day projects. That will only alter the URL part of the headers. The other parts available (refresh_pattern, and acl) are all listed in the wiki v2 attempt at youtube caching http://wiki.squid-cache.org/ConfigExamples/DynamicContent/YouTube Amos
