mtom

I am using WCF bindings with streamed transfer mode, for both uploading and downloading binary content to/from a service. I've managed to get it working. I'll include the configuration, contracts, etc for reference. I've made some tests to benchmark different bindings and encodings. Uploading results seems ok. NetTcp being the fastest, followed by BasicHttp-MTOM and then BasicHttp-Text. What suprises me is that, when downloading large files, MTOM is very slow as opposed to Text encoding with BasicHttp and Binary encoding with NetTcp. Am I missing something? Why BasicHttp-MTOM works way slower

MTOM is the W3C Message Transmission Optimization Mechanism, a method of efficiently sending binary data to and from web services. How does it work in general? If you put Wireshark (or enabled System.Net Logging ) on the non-MTOM enabled service, you should see the SOAP requests with the binary data encoded as BASE64. Sending it as BASE64 increases the size of the binary data but (I assume) makes it more interoperable. With MTOM, the SOAP messages are sent as MIME messages with the BASE64 encoding being replaced with a placeholder. The binary data is then placed between delimiters (which

I just want to know, is there any simple way for parsing MTOM/XOP SOAP response. The problem is that I use plain HTTP to send soap message and javax.xml for parsing response. But some services responds me with mulipart/related and it requires much more complex logic to parse it (performance matters). So I wonder may I somehow take advantage of apache cxf, apache axiom or any other library for parsing MTOM/XOP SOAP response? These unit tests show you how to use CXF to extract attachments out of an MTOM message. I'll inline one of the tests in case this link doesn't exist in the future: private

This question already has an answer here: BasicHttpBinding vs WsHttpBinding vs WebHttpBinding 1 answer In a WCF endpoint, what is the difference between basicHttpBinding and wsHttpBinding? When should each be used? marc_s Ton of material on that out there - just google for "WCF basicHttpBinding wsHttpBinding". You'll find amongst others: WCF : BasicHttpBinding compared to WSHttpBinding at SOAP packet level. Difference between BasicHttpBinding and WsHttpBinding and many, many more! Very basically: basicHttp is SOAP 1.1, wsHttp is SOAP 1.2 (they're quite different, esp. when it comes to SOAP
