could I use reverse-proxy to redirect cloundfoundry server to my local server?

I'm writing a nodejs web server which is published to cloudfoundry.

and a 3rd service will visit my web server.

now I want to debug at local but don't have a standalone ip.

so I wonder could I do this:

1. set up a proxy web server at cloudfoundry, call A
2. start a web server at local, call B
3. start a net connection to A, then pipe them.
4. when 3rd service visit A, the request will send to B , and response.
5. then I can develop & debug at local machine , don't need to vmc push after every save.

can I do this by writing some nodejs code? how? thx.
