usename and password.

import urllib   
sock = urllib.urlopen("http://xop-pc.main.com";)
htmlSource = sock.read()   
sock.close()

xop-pc.main.com is not an existing site.
  
Can you tell me what kind of authentication method it is using?
  
If that is the "basic authentication" (defined the standard HTTP
protocol) then you need to read this:
  
  
http://docs.python.org/lib/urlopener-objs.html
  
  
Basically, you need to subclass URLopener or FancyURLopener, and
overwrite its "prompt_user_passwd" method.
  
That method will be then called whenever the server needs
authentication.
  
  
Here is a template for you (untested):
  
  
  
from urllib import FancyURLOpener
  
class MyOpener(FancyURLOpener):
  
   def prompt_user_passwd(host,realm):
  
  return ('myusername','mypassword')
  
  
opener = MyOpener({})
  
f = opener.open("http://xop-pc.main.com")
  
try:
  
   html_source = f.read()
  
finally:
  
   f.close()
  
  
  
  
Best,

 src=""
height="80">* User Name
    pan>
    id="username" class="x4"  name="j_username" size="30"
    type="text"
value="myadmin">

    >

Les,
I tried your code and it hangs.I believe the authentication is
different from the standard one.

Any help will be appreciated.

Thanks
Amen
