Transfer encoding chunked not supported but no soap-fault thrown if they try to use it.

Optus has sent requests using chunked transfer-encoding. Requests are successful when the message size is less than one chunk. The request appears truncated to the web service if the message size is greater than one chunk.

We should be throwing a soap fault if the transfer-encoding is not supported or we should support all transfer encodings.

This is non critical as there is a simple workaround.
