[plt-scheme] Running plt web server behind a reverse proxy

Dear All,

I'm running plt web server on port 8080 on the same
server as the apache server. I need to access the plt
server for specific tasks. I'm doing this via the reverse
proxy:

http://host.xyz.ab/plt

However, the plt webserver resets the requests to
http://host.xyz.ab

Can this be done differently?
