in reply to How redirect the page in CGI programming?

You don't have to use the CGI module for everything. I personally use it only for parsing of the cgi parameters, but rarely for forming a response. 

print "Status: 302 Found\n",
        "Location: http://www.perlmonks.com/\n\n";

    Well, sure, but technically, if that is being sent directly to the browser (say, from a lightweight server using a direct socket), you need to send "\cM\cJ" not just "\n", according to the RFCs.

    This is why it's better to use CGI.pm... all that stuff just works: 

    localhost:~ % perl -MCGI=redirect -e 'print redirect("/somewhere")' | 
+od -c 
0000000    S   t   a   t   u   s   :       3   0   2       M   o   v  
+ e
0000020    d  \r  \n   L   o   c   a   t   i   o   n   :       /   s  
+ o
0000040    m   e   w   h   e   r   e  \r  \n  \r  \n                  
+

      Yes, you are right. It would only work as a CGI. However, the browser has to convert the Status-header to a http status line (such as "HTTP/1.1 302 Found\cm\cj"), as Status is CGI-specific. I don't know how these lightweight servers you mention work, but I suppose either they or the CGI module would have to issue a status line anyway.
