ASP on unix

I'm working on a proof of concept for ASP. I've already done it using Windows 2k server, IIS, using open source [no initial cost involved]. I'm looking to doing the same using a linux box. Does anyone know if this can be done without buying any additional tools?

if u wanna use asp on a unix box...i think chilisoft is the only company that had the software. they are now part of sun, so who knows if you can even use it with linux:

you might want to consider jsp, or php if you aim is to use something cross platform.

Thanks for the reply. I am also looking at PHP and JSP. I'll check chilisoft out.
