I'm looking to run node.js under IIS6 ( corporate environment, they are dead set on staying on IIS6 ). I've seen iisnode but it requires iis7.

My question is this: Is there an ISAPI redirect that can be used to connect IIS6 with node.js?

We actually ended up doing the reverse and put IIS behind Nodejs via node-http-proxy.

There are a number of benefits to doing this. For example IIS does not support web sockets, putting nodejs in front fixes this.

The only thing that you loose from node-iis is the process management, but there are plenty of alternative ways to get your node app Running reliably as a service.
