[rabbitmq-discuss] Sending HTTP Request in Rabbit-MQ

Aravind, what you're asking doesn't make a great deal of sense to me. What is it you're trying to achieve? Do you want to relay HTTP traffic via RabbitMQ to a web server, or from one web server to another, or something else? Have you considered using an HTTP enabled plugin such as the STOMP adapter to achieve this?

Anyway, if you're just trying to relay messages between HTTP/AMQP then writing an adapter shouldn't be too hard. For AMQP => HTTP => AMQP (i.e., an rpc request to AMQP that gets processed 'in the middle' by a  servlet application running in Tomcat) is quite simple to implement. Write your AMQP client code to consume the message from Rabbit. Turn the message headers into HTTP headers and transform/convert the payload if necessary, then execute the HTTP request. Once the HTTPClient return a response, reverse the process and pack everything back into AMQP. 

As I said, if you don't want to write this by hand then you can use the web-stomp plugin or something similar to expose queues/exchanges via HTTP, but I get the impression that's not what you're trying to do.
