Hi,
I wonder if this is a valid solution to the "Data missing" error that
appears when $allowcache is set to "private" and the user presses his back
button to go back to a page that was the result of a POST:
case "private":
$mod_gmt = gmdate("D, d M Y H:i:s", getlastmod()) . " GMT";
header("Last-Modified: " . $mod_gmt);
# dnaber, 2001-02-28, prevent "Data missing" error:
if( getenv("REQUEST_METHOD") == "GET" ) {
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");
header("Cache-Control: private");
header("Cache-Control: max-age=" . $this->allowcache_expire * 60);
header("Cache-Control: pre-check=" . $this->allowcache_expire * 60);
}
break;
My idea is that proxy caches should not cache POST queries by default.
Does anybody know if that's really the case?
Regards
Daniel
