steering subdomains to different cherrypy apps
Gustaf Nilsson
Im running a home server for some web apps im developing and just like
i can have different cherrypy's listening on different ports, is it
possible to have them listen to the same port but different
subdomains? (some clients with firewalls have problems accessing other
ports than 80)
thanks

Only one application at a time can listen to a TCP port.
You can certainly run a web server as a front end (like Apache, or one
of the lightweight web servers like Xitami or lighttpd), and have them
allocate your subdomain requests out to different ports.

If your various apps can somehow be assembled into one root object,
you could also look into using the VirtualHost dispatcher. See
http://tools.cherrypy.org/wiki/VirtualHosts.

The above is generally what I do. I have the varios CP instances
listening on localhost:n, localhost:n+1 etc and then just filter the
requests by Host using Nginx. This doubles as a nice way to keep the CP
instances from needing superuser permissions and leaves any logic about
the actual URL where the apps can be found out of the app code, which is
(IMHO) as it should be.

Unless you're just curious, I'm pretty sure you don't even want to
consider that approach. Using a real reverse proxy, you can keep your
applications completely separate. On Windows, IIS+Application Request
Routing is probably the path of least resistance.

Unless I'm mistaken, your real goal is to produce webapps, not web
proxies. Maybe some of the web apps are written using Python and
CherryPy, maybe some aren't (e.g. ASP.NET, Spring, etc.) Using the
right tool for the job, or at least a good tool for the job, will help
meet this goal. There are a number of good reverse proxy options
available to forward requests on port 80 to other ports of your
choosing. So unless you're really interested in reinventing that
particular wheel, then my advice would be to select one of these,
become friends with it, and let it do that work for you. Then you can
focus on developing the webapps.
FWIW, I do all my reverse proxying using nginx. It's simple to setup
and configure. But I'm running on Linux, not Windows.

But if anyone did decide to try this, they shouldn't use CherryPy's application layer, because WSGI contains some one-way transformations and limitations that prohibit creation of a generic HTTP proxy. You might be able to use CherryPy's HTTP server without WSGI, but if you wanted to pursue that, you should start with Cheroot [1], which is CherryPy's HTTP server broken out into its own project.

There is already one in existence: http://darcs.idyll.org/~t/projects/scotch/scotch/proxy.py
I'm not sure how well it actually works. A combination of cherrypy's virtual host dispatcher and this WSGI app might do what you're looking for. I'm also not familiar with the one way transformations that Robert was referring to, but if your apps don't make use of those you might get away with it.
With the ease of running an Ubuntu machine in a VM like Virtual box along with using nginx as the reverse proxy, I have a hard time using or recommending any other solution. If it were me, however, I'd host the Ubuntu server on a linode - not on my on home server.

Ok ok i am now convinced this should not be done in CP.Problem is i cant get IIS running properly, lighttpd is acting up, portfusion crashes, i hate apache, my dlink router cant do it, im running out of options!I guess nginx is next, but that will probably cost me another day of headache. :)G
