HTTPError sometimes when using urllib2.urlopen

Hi,

I have the following code -

import urllib2
from BeautifulSoup import BeautifulSoup

proxy_support = urllib2.ProxyHa ndler({"http":" http://
999.999.999.999 :8080"})
opener = urllib2.build_o pener(proxy_sup port)
urllib2.install _opener(opener)

page = urllib2.urlopen ('http://www.cornish-language.org/CORNISH/
membership.asp' )
soup = BeautifulSoup(p age)

pageText = soup.findAll(te xt=True)
print pageText

Sometimes when I run this code I get the exception -

HTTPError: HTTP Error 407 Proxy authentication required

I seem to get this error repeatidly for a while, then I go a surf for
a moment and when I run the code again the exception might have gone
away. No idea why...

I have no problems with firefox which uses the same proxy. The proxy
requires no authentication. ..

What might the issue be?

Thanks,

Barry.

Hey. Im trying to post some variables to an URL, but I get an error saying that my XML is parsed incorrectly. I know that it is not. At closer inspection I found out that some module in Python must be screwing up my request when I try to send it. Previously the code worked fine, but the problem occured when I included the proxy/authentication code, so that must be what is messing around with my request.

When I request a URL using urllib2, it appears that urllib2 always makes the request using HTTP 1.0, and not HTTP 1.1. I'm trying to use the "If-None-Match"/"ETag" HTTP headers to conserve bandwidth, but if I'm not mistaken, these are HTTP 1.1 headers, so I can't reasonably expect a web server to respond correctly to my requests. (In my limited testing, it looks like some servers respond correctly with an HTTP 304 status, while some...

I have a script that uses urllib2 to repeatedly lookup web pages (in a spider sort of way). It appears to function normally, but if it runs too long I start to get 404 responses. If I try to use the internet through any other programs (Outlook, FireFox, etc.) it will also fail. If I stop the script, the internet returns. Has anyone observed this behavior before? I am relatively new to Python and would appreciate any suggestions. ...

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
