hi all,

i have a very special question and am not sure whether this is the right place to put it, but at least i should try.

i'm running a web application on a debian "sid" box with apache 2.0 and mod_perl2. in order to provide the app with a protection against flooding, the server has to shut down the connection if a client requeststs more than one page per second. the respective code is: 
   my $r = shift;
   [...]
   my $time = time;
   if ($session->{LAST_REQUEST} >= $time - 1) {
      $r->connection->keepalive(Apache2::Const::CONN_CLOSE);
      ModPerl::Util::exit(0);
   }
   else {
      $session->{LAST_REQUEST} = $time;
   }
   [...]

[download]
quite unspectacular so far. the result is as predictable: the browser displays a blank page instead of the requested document.

a few days ago i set up a new box with the latest debian packages containing apache 2.2 and mod_perl2. and now a funny thing happens: when the server closes the connection, my firefox 2.0 browser doesn't display the blank page, but offers to download the perl sources instead. funnier: these downloads do not appear in the server's log files. even more funny: this happens with firefox only. opera 9 behaves as expected. i consider this a serious security risk. but on whose side? apache, mod_perl or firefox? and are there any workarounds?
