URL Shift is a free Chrome add-on developed by 阿尔贝鲁 that allows users to intercept HTTP requests through rules written in JavaScript. This powerful tool enables users to modify and control the behavior of HTTP requests made by web pages.

With URL Shift, users can easily create and apply rules to intercept and manipulate HTTP requests. The rules are written in JavaScript and can be obtained from a subscription rule URL. By entering the rule URL, users can access a wide range of pre-defined rules or create their own custom rules to suit their specific needs.

By intercepting HTTP requests, users can gain control over the data flow between the client and the server. This can be useful for various purposes such as debugging, security testing, or modifying web page behavior.

URL Shift provides a simple and accessible way to work with JavaScript rules for intercepting HTTP requests. It is a valuable tool for developers, security professionals, and anyone who wants to gain more control over the communication between a web page and the server.
