Hessian (web service protocol)

From Wikipedia, the free encyclopedia

Hessian is a binary web service protocol that makes web services usable without requiring a large framework, and without learning yet another alphabet soup of protocols. 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 and Python implementations of Hessian under an open source license (the Apache license). Third party implementations in several other languages (C++, .NET C#, PHP, Ruby, and Objective-C) are also available as open-source.

[edit] 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.
