After NGINX processes a set of rewriting instructions, it selects a location context according to the new URI. The request URI associated with the location is appended to the path to obtain the full name of the static file to serve. If the matched longest prefix location does not contain ^~ modifier then the match is stored temporarily and proceed with following steps. We will look at each of them individually. Once nginx decides which server processes a request, it tests the URI specified in the request's header against the parameters of the location directives defined inside the server block.
