The redirect has to be done in inner class CGIRunner of servlet CGIServlet.
Tomcat 4.1.30/5.0.28 do not handle redirect. You have to modify method run,
in while (isRunning) add your own handling. Our cgi scripts have "Status
302" for redirection, so I added header check below
if (line.startsWith("HTTP")) {
//TODO: should set status codes (NPH support)
/*
* response.setStatus(getStatusCode(line));
*/
} else if (line.indexOf(":") >= 0) {
String header =
line.substring(0, line.indexOf(":")).trim();
String value =
line.substring(line.indexOf(":") +
1).trim();
// PQ: quick fix for 302 redirect
if
(header.trim().compareToIgnoreCase("STATUS")==0 && line.indexOf("302")>-1) {
log("runCGI(my): status code=302");
response.setStatus(302);
} else {
response.addHeader(header , value);
if
((header.toLowerCase().equals("content-type"))
&&
(!value.toLowerCase().startsWith("text"))) {
isBinaryContent = true;
}
}
} else {
log("runCGI: bad header line \"" + line + "\"");
}
I know it's ugly.

Hi,

>but the redirections don't work at all.
Using an external mechanism (such as a CGI perl scripts in your case) for
redirection in Tomcat is tricky at best, and doomed to failure at worst.
The reason is that the script is not really part of the servlet
request/response pipeline. Rather, it is invoked as an exec by a Tomcat
servlet (in your case, the CGI servlet that ships with Tomcat, I assume).
That servlet can easily do a response redirect or request forward, but the
script cannot.
Accordingly, if you stick with the script at all, modify it to return the
redirection URL, and have the servlet (a custom extension to the CGI Servlet
that ships with Tomcat probably) read and act upon this URL by doing the
redirection.
