Subject [jira] [Reopened] (HTTPCLIENT-1481) Http Proxy with SSL target not working
Date Fri, 14 Mar 2014 12:32:42 GMT

     [ https://issues.apache.org/jira/browse/HTTPCLIENT-1481?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Vikram reopened HTTPCLIENT-1481:
--------------------------------


Downloaded httpclient 4.3.3, i suppose this would be the latest.

Ran the example code in "ClientExecuteProxy.java". Just replaced the target value from "localhost"
to "issues.apache.org".

Test 1 - Commented the proxy bit. The example ran successfully.
Test 2 - Uncommented the proxy part, failed with the same error as in 4.0.1. So i don't think
this is something to do with the latest version.

Getting the following exception in console when i run it,
Executing request GET / HTTP/1.1 to https://issues.apache.org:443 via http://127.0.0.1:8080

Note - For proxy, i am using tcpmon in proxy mode (no security) just specifying the listen
port.

I have posted my detailed code and usecase in stackover flow if you need any references -

> I am using HttpClient 4.0.1 and trying to configure proxy for my target https server
but its not working.
> Case being Http Client -> Http Proxy -> Https Target.
> Direct communication between the client and the target is working fine, but when i introduce
the proxy. Followed the example provided here - http://hc.apache.org/httpcomponents-client-4.2.x/httpclient/examples/org/apache/http/examples/client/ClientExecuteProxy.java
> Tried posting this on the user lists but no one seems to respond there, is this really
supported?
