Is it in anyway possible to stop a REST call?

From Javascript, I am calling a REST method which is computationally intensive. Would it be possible to stop that REST call, if you are no longer interested in what it returns.

I understand, it is possible to abort a request in JS. But it won't stop the thread which gets triggered due to the REST call. This is how I am aborting the ajax call in JS. Abort Ajax requests using jQuery

The REST interface is written in Java. And internally this thread may create multiple threads also.

I would like to stop a Java thread. But from the caller. From JS, where I have triggered it. How to properly stop the Thread in Java?

You could send a unique identifier along with your request, and then make another request that instructs the server to abort the operation started for that ID.

As Chris mentioned in the comments above, REST calls should be quick, definitely not an hour long. If the server needs to do a lot of work which takes considerably amount of time, you should modify your design to async. Either provide a callback that the server will use once it's done (also called push approach), or pull every few minutes, by sending a new request to the server to see if it's done.

In order to implement it you'll need the server to return a unique-id for each request in order to be able to identify in the callback/check-call what's the status of that specific request.

The unique-id should be implemented on the server-side in order to avoid two clients send the same ID - overriding each other.

In the link that I posted above you can see an example of how to implement a "stop thread" mechanism which can be implemented on the server-side and called by the client whenever is needed.
