Hi,
If this can be of any help, I faced similar problems for the EXPath HTTP Client implementation in Java. The problem (well, a feature, really) is that the transfer encoding "chunked" cuts down the response in several chunks, that the client has to reassemble. This is a feature of HTTP 1.1, so what you observe could be caused by either a client implementing HTTP 1.0 (which is pretty rare those days), or a client not supporting chunked encoding (if using external components, this might be as simple as enabling an option).
Hope that helps, regards,
