Hessian (Web service protocol)

Hessian is a binary Web service protocol that makes Web services usable without requiring a large framework, and without learning a new set of protocols ^{[weasel words]}. Because it is a binary protocol, it is well-suited to sending binary data without any need to extend the protocol with attachments.

Hessian was developed by Caucho Technology, Inc. The company has released Java, Python and ActionScript for Adobe Flash implementations of Hessian under an open source license (the Apache license). Third-party implementations in several other languages (C++, C#, JavaScript, Perl, PHP, Ruby, Objective-C, D, and Erlang) are also available as open-source.

Adaptations

Although Hessian is primarily intended for Web services, it can be adapted for TCP traffic by using the HessianInput and HessianOutput classes in Caucho's Java implementation.
