My testing environment for coding is currently a LAMP setup on an internal server running Linux Gnome. We've recently gained 2 or so sites to do maintenance for that were written in ASP. I'm now aware I don't have a testing environment for ASP and as I know so little about what I need to do, is it possible to run ASP on a linux machine (much like you can use WAMP to run PHP on windows)?
Check out Apache-ASP: http://www.apache-asp.org/ It's a port of ASP to an Apache module
Not used it myself but looks OK, not sure about performance in live but should be good enough for testing/dev.
