[Lazarus] Fritzbox TR64 communication

[Rolf Wetjen]

Does anyone have some experience how to communicate via TR64 SOAP with a 
Fritzbox?

I've a working Python example (fritzconnection) and I know the neccesary 
http header and data for the SOAP communication.
AVM states that "The default authentication mechanism is HTTP 
authentication using digest (MD5 hashes)".

But I've no idea and I can't find an example how to implement this with 
Lazarus. Do I need a TfpHTTPClient or a TfpHTTPWebClient object or 
someting else? Is there any documentation or tutorial for FPC networking?

Thank you,
Rolf
