One can manage network requests with Microsoft Edge using a feature called Block Network Request. Developers can control network activities. This is helpful for reasons like debugging, security, and page load optimization. In this article, we will understand how to block network activities with this option.
The blocking of requests is done in the Networks tab. This allows you to assess how incoming responses affect a website’s performance. The network tab is one of the tools present in the developer tools.
Features:
- You can view network requests as they happen with Microsoft Edge’s Developer Tools, which offer real-time monitoring.
- You have fine-grained control over what loads on a page by being able to block individual requests or entire domains.
- You can evaluate the effect on page loading times and optimize a website for better performance by blocking requests that aren’t necessary.
- By mimicking the effects of missing resources, blocking requests can help you locate possible security flaws.
Benefits:
- This feature allows developers to solve problems about broken links, mixed content errors, and resource loading.
- You can improve a website’s performance and cut down on needless resource loading by selectively blocking requests.
- By mimicking the lack of essential resources, experts in security can evaluate website behavior.

<h1 style="color:green">GeeksforGeeks</h1>
<script>
var xhr = new XMLHttpRequest();
xhr.open("GET", "https://jsonplaceholder.typicode.com/posts/1", true);
xhr.onreadystatechange = function () {
if (xhr.readyState === 4 && xhr.status === 200) {
console.log(xhr.responseText);
}
};
xhr.send();
</script>
</body>
</html>

Output : The request to https://jsonplaceholder.typicode.com/posts/1 unless the block is removed
