The current RFC would be https://tools.ietf.org/html/rfc7234, but https://tools.ietf.org/html/rfc7232#section-2 may also apply here. If you're serving the same file from multiple servers, you may have to ensure that the modification times are identical on all servers, so that the Last-Modified Headers don't change, and possibly adjust the way ETags are calculated (see https://httpd.apache.org/docs/2.4/de/mod/core.html#fileetag), since the INode numbers may be different from one server to the next. rainer --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
