Lesson plan
URI normalization
URI normalization is the process by which URIs are modified and standardized in a consistent manner. The goal of the normalization process is to transform a URI into a normalized URI so it is possible to determine if two syntactically different URIs may be equivalent. Search engines employ URI normalization to correctly rank pages that may be found with multiple URIs, and to reduce indexing of duplicate pages. Web crawlers perform URI normalization to avoid crawling the same resource more than once. Web browsers may perform normalization to determine if a link has been visited or to determine if a page has been cached. Web servers may also perform normalization for many reasons (i.e. to be able to more easily intercept security risks coming from client requests, to use only one absolute file name for each resource stored in their caches, named in log files, etc.).
