62942 - Is mozilla bypassing the Junkbuster proxy?

Status: VERIFIED DUPLICATE of bug 38488

(Core :: Networking: HTTP, defect, P3)

Description

[Frank de Lange]

It seems that Mozilla sometimes ignores the proxy settings and accesses the web
directly. I use the Junkbuster ad-busting proxy, and have told Mozilla to use
HTTP/1.0 to keep Junkbuster (which does not support HTTP/1.1) happy. But in
several cases, ads which Junkbuster would block still show up in the browser
window. If I then check the Junkbuster logfile, I do not see those ads show up
at all. This implies that they were never requested through the proxy. If I then
load the same page with Netscape Navigator, using the same proxy settings, the
ads are requested through Junkbuster, which blocks them, and the page is
pristine and ad-free...

I know that Junkbuster has problems with HTTP/1.1, but since I told Mozilla to
use only HTTP/1.0 this should not be the problem...

Actually a dup of bug 38488. There is a workaround on that bug. Can you 
reproduce with the workaround?
Thanks,
Fabian.

It seems to work when both HTTP Keep-Alive is OFF and HTTP-version is 1.0.
Setting HTTP-version to 1.0 itself (as I usually do) is not enough. So the
work-around is to set HTTP-version to 1.0, and turn HTTP-Keep-Alive OFF.

i'm not surprised that the keep-alive code would be contributing to
this problem.  it tries to keep socket transports open... and may
incorrectly reuse them when the host:port matches, but the proxy
host:port does not!  i have to verify how HTTP is selecting socket
transports to reuse.  investigating...

Marking NEW while we figure this one out. Helps get it off our unconfirmed radar.
