Prevent redirection of XMLHttpRequest

📝Title: Unleash the Power of XMLHttpRequest: Preventing Redirection with Ease!

👋 Hey there, tech enthusiasts! We've got an interesting topic to discuss today – preventing redirection of XMLHttpRequest. 🚫🌐

Have you ever wondered if it's possible to stop your browser from automatically following redirects when sending XMLHttpRequests? Well, we've got the answers for you! In this guide, we'll address common issues, provide easy solutions, and empower you to take control of your redirects. Let's dive in! 💪

🤔 Why Redirection Matters

Imagine you send an XMLHttpRequest to a server, expecting a specific response. However, instead of the desired response, your browser obediently follows a redirect and returns a completely different result. 😱 This can lead to confusion, incorrect data processing, and headaches. Fret not, for we have solutions to keep you in control.

🛠️ Common Issue: Obtaining Redirect Status Code

One common need is to obtain the redirect status code so that you can handle it yourself. This allows you to take appropriate actions based on the redirection. Luckily, with a bit of JavaScript magic, we can quickly get the desired status code.

const xhr = new XMLHttpRequest();
xhr.onreadystatechange = function() {
  if (this.readyState === 4 && this.status >= 300 && this.status < 400) {
    const redirectStatus = this.status;
    // Handle the redirect status code as per your requirements 🚦
  }
};
xhr.open("GET", "https://example.com/some-api", true);
xhr.send();

By checking the status of the XMLHttpRequest object during its onreadystatechange event, we can grab the redirect status code. This empowers you to handle the redirection in a way that suits your needs. 🙌

🔧 Solution: Preventing Redirection

But what if you want to completely prevent the browser from following redirects? Well, we've got your back! 😎

By setting the XMLHttpRequest object's followRedirects property to false, you can instruct your browser to bypass any redirections. This way, you can access the redirect status code and handle the situation yourself.

const xhr = new XMLHttpRequest();
xhr.followRedirects = false; // Prevent the browser from following redirects
xhr.onreadystatechange = function() {
  if (this.readyState === 4 && this.status >= 300 && this.status < 400) {
    const redirectStatus = this.status;
    // Handle the redirect status code as per your requirements 🚦
  }
};
xhr.open("GET", "https://example.com/some-api", true);
xhr.send();

Now, the power is in your hands! 🌟

💡 Pro Tip: Be Mindful of Cross-Origin Requests

Keep in mind that when dealing with XMLHttpRequests, you may encounter Cross-Origin Resource Sharing (CORS) restrictions. CORS rules might prevent you from accessing the data due to security measures implemented by the server. Ensure that you have appropriate access permissions and CORS handling in place.
