Scott, Here are the three different teset scripts we used
CGI:
-------------------------
#!/usr/local/bin/perl
use CGI;
my $string = "<Html><body>Simple Page</body></html>";
$query = new CGI;
print $query->header;
print("$string");
$query->delete_all();
exit(0);
---------------------------
ADP (no exec):
---------------------------
<%
set string "<Html><body>Simple Page</body></html>"
ns_return 200 text/html $string
%>
---------------------------
ADP w/ exec:
---------------------------
<%
set string "<Html><body>[exec date]</body></html>"
ns_return 200 text/html $string
%>
---------------------------
The nsd.tcl file is attached. I believe it is mostly the standard one
that comes w/ debian with a few tweeks to get CGIs enabled.
Thanks,
Matthew
