using a proxy with urllib2

[Lee, Dustin]

I'm using python2.2.2 on redhat linux 7.3

Here's a snippet of what I'm trying to run:

# set up proxy
import urllib2
proxy_support = urllib2.ProxyHa ndler({"http":" http://webproxy.mycomp any.com:3128"})
#proxy_support = urllib2.ProxyHa ndler()
opener = urllib2.build_o pener(proxy_sup port)
urllib2.install _opener(opener)
f = urllib2.urlopen ('http://some.site.com/')
print f.read(1000)

This code times out and throws a socket connection error. I've also tried setting my environment variable: http_proxy=http ://webproxy.mycomp any.com:3128 and using the default form of ProxyHandler.

I'm certain the proxy info is correct (and a proxy is needed) because I can use lynx to get it to work:

env http_proxy=http ://webproxy.mycomp any.com:3128 lynx http://some.site.com/
or
export http_proxy=http ://webproxy.mycomp any.com:3128
lynx http://some.site.com/

Without the proxy info defined for lynx it won't connect to the site in question.

Any ideas what might be tripping me up?
