No, I was not clear.  I just read the top of hello.pl and tried the suggestion
to add a 'Handle Pi3WebPerl...' line.  I had to modify it with a 'Condition',
though, otherwise *all* my files ended up saying 'Hello, World'.  ;-D

Ok, but how do I get the equivalent of the CGI 'QUERY_STRING' variable from
the request-database?  I am not familiar with the format of the HTTP request
header; which header line contains this information?  Basically, what string
do I pass to PIDB_lookup instead of "Authorization"?

Ok, I think I understand now.  Can someone point me to a good description
of how to bread down HTTP request-headers in terms of CGI?
