I just download and installed the latest Ant program on an XP Pro 32bit workstation and went to the Scripting section to enable it to use my proxy. I then press F6 to pull movie info from IMDB's script and it always return the error:
"HTTP/1.0 407 Proxy Authentication Required"
I've entered the correct username/password but same error. I'm using SquidNT 2.5 on my Win'2003 domain controller in Cygwin. The firewall is set to allow any HTTP traffic. I tried disabling the firewall for a moment too. My IE and Firefox browsers are set the same way and I can surf the net normally on the same and other workstations. But Ant just doesn't seem to authenticate on any workstation logged on to the domain.
I tried entering the username as 'domain\username' and just 'username' but same story. I also tried checking the box 'Restrict to HTTP 1.0' checkbox though I shouldn't need that.
Seems like a bug. Perhaps there should be a checkbox to use the proxy info from the browser although it shouldn't be necessary...but it may help.
Proxy Authentication
The proxy support is not done by me: I just use internet components from Indy library. Many people use that proxy option, so it should work in at least some cases. I do not know much about proxy servers so I am not sure of what can cause problems except one: if you proxy uses NTLDM authentication it may not work.
