[AlephFS] New WSE Project

Filed under: C# — stefanprodan @ 3:04 pm

I’ve stated a new research project based on Web Services Enhancements Version 3.0. The goal is to port the FTP standard on Soap. I have tried this before on the Net Framework 1.1 using DIME Attachments. The problem was that Dime could not be used with WS-* because the binary content of the message was sent outside the SoapEnvelope of the XML message. Even if the message is secure the binary attachment is not.
WSE 3.0 comes with MTOM (Message Transmission Optimization Mechanism), MTOM fully complies with WS-Security so the entire message is secure. Code upgrade concerning Dime to MTOM is easy, example follows:

public void GetFile(string fileName) 
   SoapContext repcntxt = ResponseSoapContext.Current; 

DimeAttachment dimeattch = 
 new DimeAttachment("binary", 


public byte[] GetFile(string fileName) 
    byte[] response = File.ReadAllBytes(fileName); 
    return response; 

I will post more stuff on MTOM and FTP over SOAP as the project will go on. Wish me luck.
