After the prefix match, nginx will then check for the regular expression location match in the order in which they are defined in the nginx configuration file. Configure NGINX and NGINX Plus as a web server, with support for virtual server multi-tenancy, URI and response rewriting, variables, and error handling. For example, you can define three location blocks to instruct the virtual server to send some requests to one proxied server, send other requests to a different proxied server, and serve the rest of the requests by delivering files from the local file system. This is typically used to explain options, but it can also be utilized to temporarily remove a troublesome value from the document for troubleshooting purposes.
