java.net.UnknownHostException when ProxyServer has upstream proxy

[JuanCerezuela]

WHEN ProxyServer is configured to use an upstream HTTP and SSL proxy: final ProxyServer proxyServer = new ProxyServer(browserMobProxyPort); Map<String,String> options = new HashMap<String, String>(); options.put("httpProxy", upstreamProxyHost + ":" + upstreamProxyPort); proxyServer.start(); proxyServer.setOptions(options);

THEN A java.net.UnknownHostException is thrown when I request a SSL connection from the browser:

It's still not entirely clear what your test case is. If you could attach an actual unit test, that would be really helpful.

Hi Patrick

At work all the traffic is proxied through "myproxy:8080". When I run this test, the browser is not loading the OWASP webpage on the testSSL() test case, but I can see the page is loaded on testHttp()

Cheers! Juan

P:S. happy new year :)

Hi Patrick, did you manage to reproduce the issue?

[lightbody]

Juan, Unfortunately, no. The issue is I don't know what kind of proxy you're using. Can the problem be reproduced with any proxy running at "upstreamProxyHost:upstreamProxyPort"? What proxy are you running? It would be nice if your test case included instructions for getting the entire environment set up - including the upstream proxy.

Thanks!

Patrick

I'm seeing SSL connection issues when using an upstream proxy. I'm using the Apache Traffic Server product. I can double-check this on Squid, too. But it sounds like it may just be a general issue with SSL connections being routed through an upstream proxy.

[nirvdrum]

I'm really not sure if what I was seeing was this issue. I filed mine as #79, which has been fixed in master.

Closing this out since I can't reproduce.
