transport implementation which works with proxy

[Marco Poli <ma...@ivyteam.ch>]

Hi,

since I had problems sending the requests through a proxy I implemented a 
different version of SOAPTransport.
Most code is copied from org.apache.soap.transport.http.SOAPHTTPConnection but 
it uses the java.net.HTTPUrlConnection instead of a direct socket connection.

Java uses the two System properties http.proxyHost and http.proxyPort to 
configure the proxy server.

Now if your proxy needs authentification you can set your own Authenticator:
    java.net.Authenticator.setDefault(yourOwnAuthenticator);
which gets called by the HTTPUrlConnection object, so you can also provide 
username and pw.

I'm not sure whether the next version supports proxies anyway (there was no 
sign in the cvs lastly).
So I implemented this in a separate package.

Maybe it is of interest
