Mirror site

Definition: A mirror site is a duplication (exact copy) of a site or web page hosted by a different server than the original site.

This practice can be used to lighten the traffic of a server to transfer it to another server (For example, allowing French Internet users to connect to a server in Europe that is closer and therefore faster rather than to a saturated American server).

Mirror sites were also frequently used to artificially increase the number of requests sent to the same site: the pages of these sites contain only a few keywords intended to be spotted by search engines, which are all referrals to the main site. . This technique no longer works and is akin to search engine spam.
