sorry, but i fail to see why all the trickery is needed. i assume that
you want to check the content against what is expected, but the banners
are rotating based on some formula. if you know the formula before hand,
then you know the expected distribution for the banners served. why not
use something from libwww package to make the requests, md5 the returned
banner relavant data, return a report which gives the counts for each unique md5.
so in perl pseudocode (untested, no error checking, steps skipped):
for $testnum (0..$number_to_test) {
$request_url=@bannerurls[rand(@bannerurls)];
$req = HTTP::Request->new(GET => $request_url);
$res=$ua->request($req);
if($res->is_success){
$dig=md5($res->content);
$md5{$dig}++;
}
$md5{__ERROR__}++;
}
}
foreach $dig (keys %md5){
print "the banner with digest=$dig returned $md5{$dig} hits
for",($md5{$dig}/$number_to_test)*100),"% of total\n";
}
the report should print the distribution requested. not sure if this can be done
using ab or the bench
i believe Stas was working on, but libwww is easy to use. you can even distribute
this test to a few
of your friends and have them bang on your system from a variety of different places
to test your
system in a more realistic environment. then write a program to scour the logs for
the test period,
and produce the same report from the logs. they should match almost exactly. only
differences in
incompleted log requests etc..
