We are using an implementation of Gomez here at work and for some of the configurations you have to manually go in and copy and paste into a backup document. That being said, we can't always remember to grab configs for every change so we want to automate this. I put this python script together to automate pulling the page and saving it into a document but when I try to run the code I have http debugging turned on so i get a response that it first runs and gets http 401 unauthorized error then runs a second time with the headers i have supplied. Why does it run once before including my headers?

import mechanize
import cookielib
Code:
# Browser
br = mechanize.Browser()

#Filename Declaration
filename = "Page.html"

# Cookie Jar
cj = cookielib.LWPCookieJar()
br.set_cookiejar(cj)

# Browser options
br.set_handle_equiv(False)
br.set_handle_gzip(True)
br.set_handle_redirect(False)
br.set_handle_referer(False)
br.set_handle_robots(False)

# Follows refresh 0 but not hangs on refresh > 0
br.set_handle_refresh(mechanize._http.HTTPRefreshProcessor(), max_time=1)

# Want debugging messages?
br.set_debug_http(True)
#br.set_debug_redirects(True)
#br.set_debug_responses(True)

# Set Headers
br.addheaders = [('User-agent', 'Mozilla/5.0 (Windows NT 6.1; WOW64; rv:14.0) Gecko/20100101 Firefox/14.0.1')]
br.addheaders = [('Transfer-Encoding', 'chunked')]
br.addheaders = [('Accept-Encoding','gzip, deflate')]
br.addheaders = [('Accept-Language','en-us,en;q=0.5')]
br.addheaders = [('Authorization','xxxx')]
br.addheaders = [('Cookie','xxxx]
br.addheaders = [('Host','xxxx.com')]
br.addheaders = [('Proxy-Connection','keep-alive')]
br.addheaders = [('Referer','http://xxxx.com/atscon')]
br.addheaders = [('Accept','text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8')]

# Add some 
br.add_password('http://xxxx.com', 'xxxx', 'xxxx')
br.open('http://xxxxxx/LocImpExp?op=export')

pagedata = br.response().read()

# Write to file
FILE = open(filename,"w")
FILE.write(pagedata)
FILE.close ()
print "File has been output to filename"
Let me know if i need to supply something else.
Thanks
