Hi all,

I have a question reguarding HTTP chunk-encoding support. The use of 
this mechanism is especially useful when sending swa/mtom messages with 
potentially large binary data.
The bad point is that there are currently problems using this mechanism 
for SOAP messages (at least for clients sending chunked SOAP messages). 
There isn't a unique error mechanism implemented by all servers to say 
that they do not support this encoding (error code 400, 411, 500 seem to 
be used today). It is in fact difficult to implement a fall-back 
client-side mechanism and therefore difficult to use that feature.
There might be some potential solutions (requiring web service servers 
to send 411 when not supporting this mechanism, add a place in a WSDL 
document to state whether this is supported or not, pushing that issue 
to other places...).
Any thoughts ?
