I tried going to the following four sites:
Astaro Webadmin HTTPS (on my local network)
Google Gmail (HTTPS version) (https://mail.google.com)
Outlook Web Access (HTTPS) (https://travel.itp99.com/OWA/)
CNN.com (just HTTP)
In Firefox I tried combinations of HTTP Proxy plus SSL Proxy, HTTP Proxy only, SSL Proxy only and No Proxy. Here's the results of websites that worked.
Website Both HTTP/SSL HTTP Only SSL Only No Proxy
------- ------------- --------- -------- -------
Astaro Failed OK Failed OK
Gmail OK Failed OK Failed
OWA OK OK OK OK
CNN OK OK Failed Failed
This doesn't make sense to me. I should have HTTP and SSL proxy on in Firefox and it should work with everything.
