Thanks Steve ... I actually got this working by looking through old 
archived [mapserver-users] e-mails.  I found one where someone showed an 
example of this with layer metadata in the MAP file like this ...

METADATA
    qstring_validation_pattern '.'
END

Which got everything working for me.  If I don't hear anything else 
about this, I'll assume what I did is Ok.  If that is poor form or will 
cause problems down the line I'll do it as you've specified above with a 
more complicated regex (if theres any reason to do so).  I assume this 
was done for security ?  The pattern matched (in my application) can be 
pretty variable.

Thanks,

J.B.
