Running Apache 2.2.2 proxy my clients are unable to use Yahoo Shopping. Searching and browsing product listings works fine, but as soon as they click on a particular item they get a "Forbidden" error page. STEPS TO REPRODUCE: 1. Set Apache as your proxy server and try to browse to the above URL. RESULT: HTTP Forbidden page Now try browsing to that URL with no proxy. RESULT: Works fine.
This appears to be an instance of PR #41798. *** This bug has been marked as a duplicate of 41798 ***
This is not in fact a duplicate of PR 41798. Although the symptoms are the same, the code path and therefore the fix are entirely different. This is a good report of the forward proxy bug with a testcase I could easily reproduce, so I'm re-opening it with a more generic title, in order to document the bug and its fix.
