hi ,

I trying to use urllib2 in my script , but the problem is lets say a =
domains resolves to multiple IPs , If the URL is served by plain http , =
I can add =93Host: domain=94 header and check whether all IPs are =
returning proper responses or not , but in case of https , I have to =
trust on my local machines dns resolver and I can=92t apply host header =
in the request .=20

Is it possible to override dns resolver in urllib2 or something else ?=20=


>>> req =3D urllib2.Request(url=3D'https://google.com/')
>>> f =3D urllib2.urlopen(req)
>>> print f.read()

I wanted to control the IPs which urllib2 is trying to connect .=20


I Hope I am some sense out of my question ,=20

Thanks in advance.=20
