<br>
I've experienced the following behavior with Python3 of which I do not<br>
know if it's a bug or not. On two Python3.1 implementations, Python's<br>
urllib hangs when encountering a HTTP 301 (Redirect).<br>
<br>
The code to reproduce is a one-liner (actually, two-liner), Python from<br>
Ubuntu tree:<br>
<br>
Python 3.1.2 (r312:79147, Apr 15 2010, 15:35:48)<br>
[GCC 4.4.3] on linux2<br>
Type "help", "copyright", "credits" or "license" for more information.<br>
>>> from urllib import request; request.URLopener().open("<a href="http://google.de" target="_blank">http://google.de</a>")<br>
<br>
Also occurs on another Python version (Gentoo):<br>
<br>
Python 3.1.2 (release31-maint, Jun 9 2010, 23:58:21)<br>
[GCC 4.3.4] on linux2<br>
<br>
The exchanged HTTP is:<br>
<br>
GET <a href="http://google.de" target="_blank">http://google.de</a> HTTP/1.1<br>
Accept-Encoding: identity<br>
Host: <a href="http://google.de" target="_blank">google.de</a><br>
User-Agent: Python-urllib/3.1<br>
<br>
HTTP/1.1 301 Moved Permanently<br>

Connection: Keep-Alive<br>
Proxy-Connection: Keep-Alive<br>

<A HREF="<a href="http://www.google.de/" target="_blank">http://www.google.de/</a>">here</A>.<br>
</BODY></HTML><br>
<br>
Although the content might indicate looping forever, it just hangs with<br>
no web traffic whatsoever (the TCP connection stays open, however).<br>
<br>
When interrupting with Ctrl-C, this is the calltrace:<br>
<br>

<br>
Can anyone tell me if this is a bug or expected behavior?<br>
