I have an external commercial site my users need to get to, http://www.foo.com, that unfortunately causes problems with our proxy server, users get broken links, style sheets fail to load, etc.
Through experimentation, we found using https://www.foo.com works perfectly, but some of their links are absolute, and point back to http://www.foo.com, which then causes the proxy problem when they click on them. Obviously it would be nice if the site would take care of that, but it's not likely anytime soon.
Is there a way, with the clients using IE6, to force a redirect to https://www.foo.com/whatever when a users clicks a link to http://www.foo.com/whatever? I have seen where it can be done with Firefox+Noscript.
