 Here are the files:

 Put the following in $server_root/cgi-bin/ft1 (and mark executable):
-------------------
#!/bin/sh

echo -e "Content-type: text/html;\n\n"
echo "<form action=/cgi-bin/ftg><input name=i><input type=submit></form>";
-------------------

 Put the following to $server_root/cgi-bin/ftg (marking executable) - it will
dump what vars are passed to CGI by server (an analogue of the 2nd stage
of the script): 
--------------------
#!/bin/sh

echo -e "Content-type: text/plain;\n\n"
set
--------------------

 Now at the 'g'  prompt enter the URL:
http://localhost/cgi-bin/ft1?a=v

 - the $HTTP_REFERER won't be among the env vars passed to /cgi-bin/ftg.


 Now at the 'g'  prompt enter the URL (i.e. the same URL, but without any
parameters):

http://localhost/cgi-bin/ft1

 - the $HTTP_REFERER *WILL BE* be among the env vars passed to /cgi-bin/ftg.

 You can create the trace yourself if needed.
