[squid-users] resend: squidGuard and/or authentication?

[Peter Smith]

I understand this question has been asked before, and without any response.

Any pointers?  I'm thinking of tearing up Squid 2.5.STABLE4 code to get this to work.  Probably alter the basic authentication code: if the user is authenticated to the "NOBLOCK" group, then do not use the redirector (squidGuard.); if the user is not authenticated, then route traffic to the redirector; if the redirector indeed redirects it then process the authentication; if the user authenticates correctly then go back to the top and let them through; if the user fails authentication send them to the redirected page.

Hello all.  Just a quick question--I have a need to funnel proxy traffic 
through squidGuard and if a site is blacklisted, allow access to the 
site if the user can provide appropriate authentication.  If the site is 
not blacklisted it will go through anyways regardless of authentication.

I'm currently using "redirector_access", "redirect_program", and 
"redirect_children" to implement squidGuard.  I'm looking at "external 
acl" as a possibility for handling this--perhaps a Perl app that runs 
the URL through squidGuard and if it is blacklisted then consider 
whether or not the user is currently authenticated.  If they are not 
then return the 407 to get authentication, if they are then pass them 
through.

Any ideas are greatly appreciated.
