URL rewriting is a process in web development that involves modifying the URL of a webpage to make it more user-friendly and easier to understand. This technique is often used to create shorter, more descriptive URLs that are easier to remember and share. It can also be used to redirect users to a different webpage or to customize the content of a webpage based on certain parameters in the URL. URL rewriting is commonly used in search engine optimization (SEO) to improve the visibility and ranking of a website. It is a powerful tool for enhancing the user experience and making websites more accessible and user-friendly.
