managing numerous outdated requests on the server

Within my application, there is a map feature that sends a request to the server whenever a user interacts with it, such as zooming in or panning. The issue arises when users perform rapid actions, leading to multiple requests being sent to the server and overwhelming the client with responses.

I am seeking a more streamlined approach to handling this situation at both the server and client sides. While I have ideas for improving the client's response, I am looking for solutions to avoid processing unnecessary requests on the server's end. I want to prevent any stale requests from being processed and prevent sending responses that the client no longer requires.

Currently, my application is based on the MVC architecture within the .NET Framework.

Thank you for any assistance provided.

P.S. These queries are all handled through ajax requests.

Answer №1

There are various methods to accomplish this task:

Initial method: Upon receiving a request from a client for new bounding window information, the server can implement a waiting period before processing. If another request from the same client (regarding the same zoom operation) is received during this waiting period, the previous request can be disregarded. Once the waiting period elapses without any new requests, the server can proceed with processing the current request. To minimize delays on the client side, the server can prepare resources needed for processing that are not dependent on specific zoom parameters.

Alternative method (can complement the initial approach): If the server supports it, utilizing multiple threads for processing client requests can be beneficial. This approach allows for discarding outdated results while maintaining a seamless zoom experience for the client.
