If one specifies two SOCKS proxies in a PAC file in the same return statement, only the first one is attempted. Reproducible: Always Steps to Reproduce: 1. In a PAC file, specify two SOCKS proxies as such "return SOCKS socks1.blah.com; SOCKS socks2.blah.com". 2. If socks1.blah.com goes down, socks2.blah.com should handle the request, but it does not. Actual Results: Instead of socks2.blah.com handling the request, it just errors out, indicating that the proxy is not responding. Expected Results: Failover to socks2.blah.com this bug might be a dupe of bug 273258, but that one had been resolved as a dupe of another bug that was supposedly fixed.

Hi Daniel, Do you think this is a dup of bug 1230803?

Yes, to the extent that this is one of the problems I think should be covered in work mentioned in that bug.
