hello,All:
we are looking at the proxy support in apache client and here is my
understanding of what the user client needs to do:
1. http/https proxy
client.getHostConfiguration().setProxy(hostName, port);
2. reverse proxy
nothing needs to do in the http client code since it is transparent.
3. socks proxy
nothing if according to what Roland mentioned below"SOCKS connections are
transparent
to HttpClient", then how do you know it is using socks proxy or a direct
connect?
4. secure proxy(basic auth)
client.getState().setProxyCredentials(new AuthScope(hostName,port), new
UsernamePasswordCredentials(user, password));
5. secure proxy(NTLM auth)
client.getState().setProxyCredentials(new AuthScope(hostName,port), new
NTCredentials(NTuser, NTpassword,hostName, domain));
The wield thing is if I do
client.getState().setProxyCredentials(new AuthScope(hostName,port), new
UsernamePasswordCredentials(NTUser, NTpassword));
or
client.getState().setProxyCredentials(new AuthScope(hostName,port), new
NTCredentials(user, password,hostName, domain));
they both work fine. why?
thanks a lot,
Michelle

Hello Michelle,
> Seems essentially we call the same API setProxy for both http proxy and

No, that is wrong. If you want to use a SOCKS proxy, you follow the
instructions in the JDK documentation. SOCKS connections are transparent
to HttpClient. If you want to use an HTTP proxy, you follow the
instructions in the HttpClient documentation, because HttpClient needs
to know about it. HTTP proxy connections are NOT transparent, the request
to an HTTP proxy looks slightly different from a direct request to a
server.
hope that helps,
Roland
