The session ids that I'm using here are those generated by
Apache::Session itself. They appear to be a md5 hash of some sort (I've not really looked into *how* they are generated). That's the only piece of info ever stored in a cookie, and validating if the cookie has been tinkered with is easy.
eval {
# tie to session_id (sorry it's monday morning don't remember the
+exact syntax)
}
if ($@) {
print "bogus session\n";
}
basically if you ask apache session to access a session that doesn't exist it dies. Thus the eval...
/\/\averick
perl -l -e "eval pack('h*','072796e6470272f2c5f2c5166756279636b672');"
