[plt-scheme] plt web server question

The servlet program is attached. I put the file under "C:\Program 
Files\PLT\collects\web-server\default-web-root\servlets", and run 
"C:\Program Files\PLT\PLT Web Server Text.exe" or "C:\Program 
Files\PLT-3.99.0.26\plt-web-server.exe". Then using URL 
"http://127.0.0.1/servlets/repl.ss" to access it in by browser. So no 
fancy stuff here. There is only one call to "send/forward" in my whole 
servlet, which caused the error, but I couldn't see why.

Thanks,
Chongkai
