>Description:
just use a cookie name very small like 'e=952342324' with another cookie say
'foo=AZeRZRi'. If you are lucky, your browser will give to apache the second
cookie first and mod_usertrack will match (strstr) the name 'e' in the value
of the first cookie and this is bad.
>How-To-Repeat:
no example, it is so simple to do it
>Fix:
should match something like ' e=...' not just 'e'
