Re: [cross-project-issues-dev] Proxy Testing Tool?

Hi Scott,

yes, I am aware of that discussion. AFAIK, we never arrived at real test
scenarios, though, which allowed us to open upstream bug, for example.

Code Recommenders and the Automated Error Reporting use HttpComponents
internally, either directly or through Eclipse Aether (in Code
Recommenders' case).

We use ECF *only* for our communication test, as we got the impression
that ECF is sometimes more successfully in traversing proxies. Our
communication test now uses ECF and HttpComponents and "calls home" on
*both* channels. If one or both messages get through, we have a data point.

Now, the question is how to interpret these data points. Unfortunately,
it doesn't look like we can make blanket statements like "NTLM never
works". It's rather "it depends". The question is just "on what?"

I don't thing we have reached the "provide a patch" stage just yet; we
are still at the "pinpoint the problem" stage. If anyone can make of the
data more than I can, any pointers would be greatly appreciated.
