Re: Behavior of HTTP BC

[Vincent GIRARDREYDET <vi...@thalesgroup.com>]

The HttpBridgeServlet is the servlet that gets registered in Jetty when 
the server is started. The servlet is constructed with a HttpProcessor 
(the one implemented by the HttpEndpoint beeing deployed) and _bridges_ 
the servlet requests to the HttpProcessor.

So for each HTTP endpoint you have a HttpBridgeServlet registered in 
Jetty with the mapping provided in the endpoint configuration.

Hope this helps :-)
