If I run this against a password protected HTTP(S) site from a host

move it behind a proxy that requires authentication. The Twisted
documentation did not make it clear (to me) how to add proxy
authentication and I cannot find an example on the Internet.
I've tried adding an additional Proxy-Authentication header to the
call, but that doesn't help Any ideas would be greatly appreciated.
"Didn't help" how? What didn't work?
What kind of proxy is it?
Didn't help in that I receive an HTTP 407 Proxy Authentication required.
It is a proxy that requires Basic HTTP authentication.
Maybe you meant to add the "Proxy-Authenticate" header instead of the
"Proxy-Authentication" header?
Twisted Web provides no particular support for authenticating with proxies,
but it doesn't do anything that would prevent you from handling this in your
code, either.

proxyUsername = 'bob_hancock'
proxyPassword = 'myproxypass'
proxyAuth = base64.encodestring('%s:%s' % (proxyUsername, proxyPassword))
proxy_authHeader = "Basic " + proxyAuth.strip()
url = "https:/www.myexampl.com" #password protected site
username = "bob_hancock"
password = "myremotepass"
basicAuth = base64.encodestring('%s:%s' % (username, password))
authHeader = "Basic " + basicAuth.strip()
return client.getPage(url, headers={"Authorization": authHeader,
"Proxy-Authenticate": proxy_authHeader})
Is this the approach? I'm behind a corporate proxy/firewall so that
if I make a direct HTTPS request I receive an HTTP 407 response.
Thanks for the rapid reply. This is my first attempt at Twisted.
This looks largely correct to me. I don't have a proxy (and I definitely
don't have /your/ proxy) to actually test it against, so I may be missing
something. One thing that does come to mind is that a proxy might require
that the request URL is absolute rather than relative (<http://foo/bar>
instead of </bar>). I'm not sure when exactly this is required, nor how
to convince `getPage´ to make a request of that form. This might be related
to <http://twistedmatrix.com/trac/ticket/2714>.
