CGI with URL problem

[rodmc]

-- sorry if this has shown up twice, but my browser crashed and ended
up posting the message when I hit the space bar for some odd reason.
Also it was not quite ready.

Hi,

I am writing a small CGI app which tests if another webpage exists,
the pages are on a Wiki system. Anyway when I run the same function
(see below) from within IDLE it is ok, however when it is run from
within the CGI script I get a socket error::

"URLError:
reason = <socket.error instance>"

I am not quite sure what is causing this, is there a special way of
dealing with such things from within CGI script? I have pasted the
offending function below, along with only the import statement which
relates to that function.

Thanks in advance for any help.

Kind regards,

rod

From the CGI version:

from urllib2 import urlopen as urlopen

def urlexists(url):
path="http://x.y.z/wiki/index.php?title="+url
sock = urlopen(path)
page=sock.read()
if "There is currently no text in this page" in page:
return True
else:
return False

Ammended IDLE version:

from urllib2 import urlopen as urlopen
import os,sys

def urlexists(url):
path="http://x.y.z/wiki/index.php?title="+url
sock = urlopen(path)
page=sock.read()
if "There is currently no text in this page" in page:
print "found"
return True
else:
print "not found"
return False

if __name__=="__main__":
urlexists("cheese_test")

Are you using the same user in your cgi script and within IDLE?

Thanks for your reply, no one is running locally on my PC and the
other as the default user which occurs when the script is run through
a browser.

Best,
