I have a web service that accepts POST requests. This is a network internal service where internet attacks are not a concern at this layer. However, it's not always fast. The user doesn't need the entity info of the POST response. I'd like to put in place a proxy that accepts any POST, returns 202 status, and forwards the request asynchronously to the real service.
I can't find a proxy that does this! Either it's a message queue of some sort, where the destination needs to poll, or its a proxy like squid or nginx that waits for the remote service to complete.
What am I missing? Is there one somewhere? Does nobody else have the need to asynchronize POST processing?
