 * https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/If-None-Match
 The If-None-Match HTTP request header makes the request conditional. For GET and HEAD method, the server will send back the requested resource, with a 200 status, only if it doesn't have an ETag matching the given ones. For other methods, the request will be processed only if the eventually existing resource's ETag doesn't match any of the values listed.

	The If-Modified-Since request HTTP header makes the request conditional: the server will send back the requested resource, with a 200 status, only if it has been last modified after the given date. If the request has not been modified since, the response will be a 304 without any body; the Lst-Modified response header of a previous request will contain the date of last modification. Unlike If-Unmodified-Since, If-Modified-Since can only be used with a GET and HEAD.
