A mirror page is a duplicate webpage that is created to serve as an exact copy of another webpage. It is typically used for backup purposes or to reduce server load by distributing traffic across multiple servers. Mirror pages are also commonly used in content delivery networks to improve website performance and reduce latency for users. In some cases, mirror pages may also be used for malicious purposes, such as creating fake versions of legitimate websites to trick users into providing sensitive information. However, in most cases, mirror pages are a legitimate and useful tool for website owners to improve their website’s functionality and accessibility.
