[python] How to detect a remote webpage is accessible? (in HTTP)

[Astan Chee]

How about:

import socket, urllib2

timeout = 10
socket.setdefaulttimeout(timeout)
try:
auth_handler = urllib2.HTTPBasicAuthHandler()
opener = urllib2.build_opener(auth_handler) #this used if we need 
authentication
urllib2.install_opener(opener)
req = urllib2.Request('http://website.com')
f = urllib2.urlopen(req)
notes= f.readlines()
f.close()
print "Everything is ok"
except IOError, r:
p = str(r)
if re.search(r'urlopen error timed out',p):
print "Web page timed out"

You'll need to set up the timeout to whatever duration your website 
takes to load.
Cheers
