DevTip: Avoid HTTP Blocking

Hey Devs,

Today, we will discuss how to avoid HTTP Blocking. But First of all, let's discuss :

What is HTTP Blocking?
HTTP Blocking is when your web requests are put on hold until previous ones are completed. Imagine standing in a queue where you can't move forward until the person in front of you does. That's HTTP Blocking for web requests.

How it Occurs?
It usually happens when your web application tries to make too many requests to a server all at once. Since the server can handle only a limited number of requests at a time, the excess requests have to wait their turn.

How to Resolve:

  1. Asynchronous Requests: Make your requests asynchronous, letting other processes run while waiting for a server response.
  2. Batching and Caching: Group multiple requests into a single one if possible, and cache frequent requests to reduce server load.

Best Practices:

  • Create a Message Queue: Set up a message queue to manage and process heavy requests asynchronously.

  • Avoid unnecessary API calls by optimizing your application logic.

  • Use modern HTTP/2 protocol, which supports multiple simultaneous requests over a single connection, reducing blocking.

  • Monitor and adjust server settings to handle peak loads efficiently.
