NetCache Proxy: Timeout with certain website

Hello everyone

I've looked through the Internet as far as I could without finding a solution, maybe I find it here. The name of the forum sounds like it ;-)

OK - to the point.
I'm using a NetCache Proxy and using a Proxy Pac in the browser. The proxy pac includes an ACL list which defines which websites are allowed (domain names, keywords in urls etc).

My problem now: A user wanted to access the E-Banking under www.ubs.com. This domain (and subdomains) are allowed. The site works fine UNTIL the user clicks on the login for the e-banking. The url for this login is https://ebanking1.ubs.com/classic/?login. When he clicks on the link nothing happens. Wait.. wait... wait... And at some time Internet Explorer froze.

I thought it might be a problem simply with HTTPS sites but thats not the case, other pages work fine with and without https.

I then checked the NetCache logs and found the following entries:

Someone who knows proxy logs will see one simple but important thing: There is no GET as it should be when accessing a website. See following example (normal http site of ubs.com):

Now I hope someone here has an idea, why the connection doesn't work or why there is no final GET from the proxy. Am really out of ideas now.

Thanks in advance!


Update: It works on Firefox! But not on IE (6). Both have the same connection settings (the proxy pac). Any ideas?
