Unable to connect to internet URL behind firewall

[priyanka.khamankar]

Hi,

I am using below two approaches to connect to read the content of internet url.
These two approaches work for me when the internet explorer session is open.

When the internet explorer window is closed, below code gives me 407 error.
I have also set the HTTP_PROXY environment variables as http://proxy-example.com:3128

Is there any way that the Python does not use Internet explorer proxy settings?
I want my python script to work even when the IE window is closed.Please help.

I am using Python version 2.6. Python code I am using is provide below.

Approach 1:
import urlib2

# == HTTP ==
#
# HTTP with auth info in ProxyHandler is working
#
proxy_handler = urllib2.ProxyHandler({'http': 'http://user:[email protected]:3128/'})
opener = urllib2.build_opener(proxy_handler)
response = opener.open('http://example.com/testpage.htm')
print response.read()

Approach 2:
# HTTP with AuthHandler is working
#
proxy_handler = urllib2.ProxyHandler({'http': 'http://proxy-example.com:3128/'})
proxy_auth_handler = urllib2.ProxyBasicAuthHandler()
proxy_auth_handler.add_password('realm', 'proxy-example.com:3128', 'user', 'pass')

opener = urllib2.build_opener(proxy_handler, proxy_auth_handler)
response = opener.open('http://example.com/testpage.htm')
print response.read()

Hi,

My guess is that your firewall is blocking the connections. To check this,
disable your firewall and run your python program. If it runs, you have to
configure your firewall to allow your program to connect to the internet.

Hi,

I am using below two approaches to connect to read the content of internet
url.
These two approaches work for me when the internet explorer session is
open.

I have also set the HTTP_PROXY environment variables as
http://proxy-example.com:3128

From experience the environment variable name is in lowercase. Try

http_proxy instead.

Don't ask me why this environment variable is lowercase when most others
aren't.
