We have squid setup for a test in reverse mode for using outlook web access. We have it setup to use authentication into active directory. Basically, if you are part of a certain AD group you get denied access to OWA via the proxy. So how this works is someone browses to OWA via HTTP (which is the proxy) and they get a pop-up prompt to login/authenticate. Once they authenticate the page that loads redirects them automatically to the HTTPS version of OWA, but squid pops-up the authentication box again because, what I guess, is that it's a new protocol (https) and needs to reauth the user.
This is annoying to have 2 pop-ups. If the user just hits the HTTPS version of the URL its fine, but most people don't, and rely on the transparent HTTP->HTTPS redirection. Ideas on how to make this go away? Can I configure squid to do the redirection before authentication? If so, how? - Nick
