Multiple file based sites on node server

I am looking to create multiple sites on a single server running node.js. Three of the sites could be easily served by running a file based server such as http-server but there are other sites which will be web services based, so just creating a single http-server with multiple directories for each site is not an option.

Does node-http-proxy combined with http-server work best for this case, or is there a better way?

My thought was to set up node-http-proxy as:

• www.site1.com -> http://localhost:3000
• www.site2.com -> http://localhost:3001
• www.site3.com -> http://localhost:3002
• www.site4.com -> http://localhost:3003

Then create multiple instances of http-server listening on each of the 4 ports.

• http-server site1 (on port 3000)
• http-server site2 (on port 3001)
• http-server site3 (on port 3002)
• myWebService (on port 3003)

Is this the proper approach?

Are there any advantages/disadvantages of doing it this way over just coding a custom node.js listener that determines what to do for each of the sites without forwarding the requests to another listening node server?

i.e. Does the reverse proxy add a lot of overhead? Does creating multiple http-server instances incur additional cpu overhead? etc.

Is there a better way??
