Yes, this is the part that that's relevant: https://github.com/nmaier/mod_xsendfile/blob/master/mod_xsendfile.c#L558 If there was a valid ETAG at this point, it would trigger the conditional request handling. It looks like preceding this line the module is trying to get the core to set the same ETAG it would have set if serving the static file directly. --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscribe@xxxxxxxxxxxxxxxx For additional commands, e-mail: users-help@xxxxxxxxxxxxxxxx
