From your Python code, you would like to pretend to the web server that you are browsing from Mozilla Firefox.
You can send the custom user-agent values in the HTTP request header.
Listing 4.7 explains spoofing Mozilla Firefox in your client code as follows:
#!/usr/bin/env python
# Python Network Programming Cookbook -- Chapter – 4
# This program is optimized for Python 2.7.
# It may run on any other version with/without modifications.
import urllib2
BROWSER = 'Mozilla/5.0 (Windows NT 5.1; rv:20.0) Gecko/20100101
Firefox/20.0'
URL = 'http://www.python.org'
def spoof_firefox():
opener = urllib2.build_opener()
opener.addheaders = [('User-agent', BROWSER)]
result = opener.open(URL)
print "Response headers:"
for header in result.headers.headers:
print " ",header
