I want to make squid ask for authentication only for certain content-type of the http response. For all other content-type I don't want the browser to raise authentication popup window. The solution I've in mind is to make an external acl helper that retrieves only the http header of the url and scan it for content-type. To do so I'll have to patch squid to implement the %PATH external_acl_type fromat parameter (backporting some code from actual devel-branch to my squid version 2.5-stable3 on redhat enterprise 3 U3). I know this is a communication overhead, but I can't figure out a better solution. Anybody has a better solution? Thanx, -- Adolfo ___________________________________ Yahoo!
