+/// Last-Modified Response Header\r
+/// The Last-Modified response HTTP header contains a date and time when\r
+/// the origin server believes the resource was last modified. It is used\r
+/// as a validator to determine if the resource is the same as the\r
+/// previously stored one. Less accurate than an ETag header,\r
+/// it is a fallback mechanism. Conditional requests containing\r
+/// If-Modified-Since or If-Unmodified-Since headers make use of this field.\r

+\r
+///\r
+/// If Unmodified Since Request Header\r
+/// Makes the request for the resource conditional: the server will send\r
+/// the requested resource or accept it in the case of a POST or another\r
+/// non-safe method only if the resource has not been modified after the\r
+/// date specified by this HTTP header. If the resource has been modified\r
+/// after the specified date, the response will be a 412 Precondition Failed error.\r
