loading a url using urllib2

I have the following code to load a url (address).

When I have a url like this,

http://www.testcom.co.uk/dev_12345/www.cnn.com

i get an error "Failed to open http://www.testcom.co.uk/dev_12345/www.cnn.com";.
Is there something wrong with my URL? or something wrong with my code?

Thank you for any help.

cj = cookielib.LWPCookieJar()

opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cj))
urllib2.install_opener(opener)


txheaders = {'User-agent': 'Mozilla/4.0 (compatible; MSIE 5.5;
Windows NT)'}
try:
print "address", address
print "txdata", txdata
print "txheaders", txheaders
req = Request(address, txdata, txheaders)
handle = urlopen(req)
except IOError, e:
print address
print 'Failed to open %s' % address
data = ""
