Filtering URLs using Firefox extension

As the page loads, multiple HTTP requests are made for the document and its dependencies. I am looking to intercept these requests, extract the target URL, and stop the request from being sent if a specific condition is met. Additionally, plugins may also make HTTP requests, so I want to address those as well.

Answer №1

When it comes to redirecting traffic, there are a variety of methods at your disposal:

* On the server-side: You can configure your web server to send a 300 HTTP response code (such as 301 for "moved permanently" or 302 for "found" or "moved temporarily"), along with a Location header pointing to the new URL.
* On the client-side: You have the option to use the http-equiv="refresh" attribute in a meta tag, or manipulate the JavaScript window.location object (either with or without the replace() method) within the HTML document's head section.
