Hessian cloth or Burlap (chiefly US) is a coarse woven fabric usually made from jute or hemp and allied vegetable fibers. The name 'hessian' is attributed to the use of the fabric, initially, as part of the uniform of soldiers from the German state of Hesse. The name 'burlap' appears to be of unknown origin.
German soldiers loyal to King George III who fought for Britain in the Revolutionary War. King George was from Hanover, an area in Germany, and called in a favor to his homeland, asking for soldiers willing to fight in the New World. The Hessians numbered almost 30,000, and they fought mostly in the Northern Campaign. They are most famous, however, for being surprised and defeated at Trenton by American forces under General George Washington, whose army had just crossed the Delaware River in the dead of night on Dec. 25, 1776.
The Hessian binary web service protocol 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.
