title: Is it appropriate to use message queues for synchronous rpc calls via ajax
body: <p>I have a web application that uses the jquery autocomplete plugin, which essentially sends via ajax a request containing text that has been typed into a textbox to our web server, once the web server receives this request, it is then handed off to rabbitmq. </p>
  
  <p>I know that we do get benefits from using messaging, but it seems like using it for blocking rpc calls is a misuse and that something like WCF is far more appropriate in this instance, is this the case or is it considered acceptable architecture?</p>
