[news.eclipse.technology.ecf] ECF Filetransfer Proxy

[cgs.schaefer@xxxxxxxxx (Christian Schaefer)]

We are using Equinox P2 to update our RCP Application programatically from 
a remote repository via HTTP.

Now that we have P2 up and running, we do not find any documentation on 
how we can configure proxy support for ECF etc. 

within our environment some workstations work correctly with P2 on some of 
them we get 

Caused by: org.eclipse.ecf.filetransfer.BrowseFileTransferException: 
Proxy Authentication Required	at 
org.eclipse.ecf.provider.filetransfer.httpclient.HttpClientFileSystemBrowser.runRequest(HttpClientFileSystemBrowser.java:202)

now we got this switch as a tip
-Dorg.eclipse.ecf.provider.filetransfer.excludeContributors=org.eclipse.ecf.provider.filetransfer.httpclient

it works somehow but we don't know why.

1. Is there any documentation about proxy konfiguration and ECF ?
2. where can we find the possible configuration options for ECF ?

thanks!
