timeout exception because of no Content-Length

[krishna <kr...@lac.uic.edu>]

Hi Samisa/Fred/All,

Both the methods
1. Using the stubObj to setTransportTimeout
2. Calling setTimeout from the stub code

Gave me the following error.

Error
HTTPTransportException:Input streaming error while getting data Timed 
out waiting for SOAP message (1).

My analysis showed that the code with for http chunking has 2 parts.
1. For the initial chunk
2. For the subsequent chunks

It relies on the content length field to decide whether the current 
chunk is the first chunk or not
Please find the lines below from HTTPTransport.cpp

if( m_strReceived.length () > 0)
{
627
628 if( m_bChunked && m_iContentLength < 1) // Read first chunk
629 {


.......
722 }
723 else if( m_bChunked) // read continued portions of a chunk
724 {

As the SOAP - RESPONSE does not contain a Content-Length field. It keeps 
repeating the algorithm for the first chunk
and lands in an exception.

If my analysis is right then my question is why does the server not send 
a Content-Length field for chunked messages and how can this be 
incorporated?

Cheers
Krishna
