i add some logs:

If run it locally, set the browser's proxy to localhost, and visit=20
"www.google.com", the log says:
proxy is running
> ready to proxy req to www.google.com
> ready to proxy req to www.google.com
> ready to proxy req to www.google.com
=20
If run it on Nodester, the log says:
nodester info Showing logs for: kapp
> New PID: 7659
> chroot_runner
> chroot_runner
> Spawing /app/test.js
> Running node v-0.6.17
> proxy is running
Then set the browser's proxy to Nodester, and visit "www.google.com". Check=
=20
logs again, the result is no new logs output, the app seems does not=20
receive any request.
I know that Nodester setup an association between "appname.nodester.com:80"=
=20
and "the_actual_app_host:app_port", but it seems can not transparently=20
route http requests?
Purpose: Because i can not visit some sites directly from my host, i just=
=20
want setup a http proxy on Nodester to route http requests to these sites.
Or Nodester can not do this? Only web apps?
