I presume your intent by outputting Status:200 is to generate a header? But 
the headers are generated by the server, not the script.

Also, you do not output a Content-type which is generally an error; in this 
particular case however the Location line is treated specially by the CGI 
environment and indeed is the only part of your output to be sent to the client.

If you really wanted to generate your own headers, the script would have to 
be called nph-foo.

Since you asked what the NCSA and CERN servers do (an thus presumably cannot test 
this for yourself) here are the results.

You get a 302 because you output the special string Location:
