It is better to close this issue as it was a Server Error. Standard just says that when there two headers with different values, combine them comma separated as urllib2 does.  Making special case exception for 'Content-Length' header when the server is at fault would be bad idea. We will not know which value to choose from if the values are different.

Closing this bug as Invalid.


>>> import urllib2
>>> req = urllib2.urlopen('http://wwwsearch.sourceforge.net/mechanize/src/mechanize-0.1.11.zip')
>>> req.info()['content-length']
'289519'
