#11 Chunked http responses cause a protocol parse error

[Jeffrey Sinclair]

Http.php is written to perform an HTTP POST using HTTP/1.1 which means that the Hessian client must support a HTTP header of "Transfer-Encoding: chunked".

Protocol::parseReply() is written as follows:

if($this->read(1) != 'r') {
return new HessianError('Hessian Parser, Malformed reply: expected r',HESSIAN_PARSER_ERROR,0,$this->stream);
}

which will fail because the first line of a chunked response will contain the chunk length. Protocol::parseReply() needs to be written to support chunking.

At the moment the workaround I have is to set HTTP/1.0 in Http::POST.

Example stack trace:

Fatal error: Uncaught exception 'HessianError' with message 'Hessian Parser, Malformed reply: expected r' in /opt/hessian-php/1.0.5-RC2/dist/Protocol.php:339

I've also experienced this error. Thank you very much for posting this workaround.
