Thanks for the response

Unfortunately, I can't use your approach as my "test" and "production" scripts are in the same server, but under different directories. Hence, "HTTP_HOST" returns the same value for both "test" and "production".

But, I noticed that env variables, "REQUEST_URI" and "SCRIPT_FILENAME", has the "test" or "prod" string string attached to them (i.e, if the script name is test.cgi, the REQUEST_URI string has a value of "/testenvir/test.cgi" in 'test' environment and "/prodenvir/test.cgi" in 'prod' environment, respectively).

I am going to check if I can use your logic with the above ENV variable(s).

Is that a good approach?
