Zend_Rest_Client problem with sending XML content with encoding type specified (content-lenght is 0)

Question

I would like to sent request to our clients server, but they require to send XML as application/xml

I was trying to use setEnc() method but I've got error on unsupported content type, so then I've tried to se setRawData() as they suggested:

self::getHttpClient()->setRawData($XML, 'application/xml'); $this->restPost($this->getPath());

But the way ZF is implemented I'm loosing content-length information (resetParameters part)

final private function _prepareRest($path) { ........ self::getHttpClient()->resetParameters()->setUri($this->_uri); }

Any solution?
