Rexy

A C# REverse proXY for SOAP requests, over a RabbitMQ message broker. The project consists of two main projects, the proxy endpoint (RabbitMQ.Adapters.HttpHandlers) and the SOAP forwarder (RabbitMQ.Adapters.WebServiceCaller).

This allows to decouple webserver clients and servers and supports and incremental move from an architecture based on webservices to one based on a message queue.

Features

• Configuration of routes (which call gets forwarded to which server) on the reverse proxy
• Support for windows authentication
• Modifying response with wsdl data to use web addresses of the reverse proxy instead of the original SOAP server.
• Support for gzip-compressed responses

Overview

Example of a typical setup:

                   ReverseProxy     RabbitMQ                                   
 SOAP Client       HTTPHandler         ++     WebServiceCaller      SOAP Server
                                       ||                                      
 +--------+         +--------+         ||        +--------+         +--------+ 
 |        |  SOAP   |        +-------->||        |        |  SOAP   |        | 
 |        +--------->        <---------||        |        +--------->        | 
 |        <---------+        |         ||-------->        <---------+        | 
 |        |         |        |         ||<-------+        |         |        | 
 +--------+         +--------+         ||        +--------+         +--------+ 
                                       ||                                      
                                       ++
