There's a problem with urllib on Windows. Here's a quote which relates to the problem: """ In the newest version of the urllib. They added a section which pulls the http web_proxy from the windows NT registry. Unfortunately they did not think to check for 127.0.0.1 and remove it from the proxy list and they also did not handle (no proxy addresses). As a result the new library reads the proxy settings from the Windows NT Registry for IE and attempts to use them. """ Any thoughts on how to solve this ? |

Logged In: YES user_id=14198 This is not a problem with the win32 proxy detection code, but with urllib in general. urllib itself does not handle the concept of "proxy exclude list", and nor does it handle the localhost case - if a proxy is configured, it uses it. So either you are after an enhancement to urllib to allow certain addresses to bypass the proxy, or a technique to allow the registry to be ignored. I believe the latter can be handled by setting "ignored_proxy=something" in the environment. Can you clarify exactly what you want here? If it is the urllib enhancement then I am not the best person for this - I don't have a proxy server available, and don't have much code that uses urllib. |

Logged In: YES user_id=38388 Well the point is that if you have IE configured to use a proxy then urllib will automagically use it for all requests. This is obviously not ideal for certain requests like one to the localhost. Looking at the code I cannot find any way to switch off proxies by using environment variables (ok, you can specify "http_proxy=", but that will only result in an error that the proxy is not found). So in the end, I think this is a bug in the sense that you cannot turn proxy handling off and a feature request in the sense that it should be possible to turn it off ;-) IMHO, the localhost and 127.0.0.1 should always be excluded from the proxy handling. |

Logged In: YES user_id=14198 Looking at the code, I suspect "blah_proxy" will disable the registry. This will setup the scheme "blah://" to use a proxy, and avoid the registry code completely. As "blah://" is invalid, http etc requests should work fine. While I agree in general with the fact that localhost should never be proxied, that makes this bug no longer Window specific, and not related to the IE code at all. Hence I am probably not the best person to have this assigned to - if you want it fixed that is :) |

Logged In: YES user_id=14198 This patch appears to have been addressed in checkin 1.129 of urllib.py. Checkin message, by tim_one, is: SF patch #403640: incomplete proxy handling in URLLIB Look specific to Windows. Don't know whether it works. |
