urllib accept-language doesn't have any effect

[Martin Bachwerk]

Hello,

I'm trying to load a couple of pages using the urllib2 module. The 
problem is that I live in Germany and some sites seem to look at the IP 
of the client and forward him to a localized page.. Here's an example of 
the code, how I want to access google.com main english page, but get 
German instead. (For those of you who live in US, you will probably get 
correct results.. try emulating with 'fr' in accepted languages or 
something)

opener = urllib2.build_opener()
opener.addheaders = [('Host', 'www.google.com'), 
('Accept-Language','en-gb,en;q=0.5'), ('User-agent', 'Mozilla/5.0 
(Windows; U; Windows NT 5.1; en-GB; rv:1.9.0.1) Gecko/2008070208 
Firefox/3.0.1')]
webfile = opener.open(url)

Any help would be greatly appreciated!

Thank you!

Martin
