Hi Paul,
You are technically correct, it should not start with a '?'. The current
code simply ignores the question mark and, in fact, ignores all characters
until the first '&' (which, in itself is incorrect based on the structure
of the information. So, some adjustments would be needed here. Since the
the code treats the question mark as optional ((I assume dCache does the
same) then we should eliminate it as it will still be backward compatible.
On the other hand, keeping it would simplify allowing that the first CGI
element need not have an ampersand. Something to cogitate.
