[privoxy-devel] bug in php compression?

[Fil <fi...@re...>]

Hi,

I'm one of the developers of "spip", a CMS based on PHP (see
http://uzine.net/spip if you want to know more). We're trying hard to
circumvent the php bug with ob_gz_handler, but one of our users tells us
that he has problems with privoxy.

Here's the code where we detect if we should use the handler. What can we
add to be privoxy-safe? (And, why doesn't privoxy handle compressed pages,
haha).

Thanx.

//
// Reglage de l'output buffering : si possible, generer une sortie
// compressee pour economiser de la bande passante
//

if ($flag_obgz) {
    $use_gz = true;

    // si un buffer est deja ouvert, stop
    if (ob_get_contents())
        $use_gz = false;

    // special bug de proxy
    if (eregi("NetCache|Hasd_proxy", $HTTP_VIA)) {
        $use_gz = false;
    }
    // special bug Netscape Win 4.0x
    if (eregi("Mozilla/4\.0[^ ].*Win", $HTTP_USER_AGENT)) {
        $use_gz = false;
    }

    if ($use_gz) {
        @ob_start("ob_gzhandler");
    }
    @header("Vary: Cookie, Accept-Encoding");
}
else @header("Vary: Cookie");

//
// end output buffering
//


(If you want to try: http://uzine.net/spip is itslef a good example.)
