I havent heard about it. In fact, i thought it was impossible to use asp on an apache server, Guess it makes sense. I have seen a lot of asp pages on a lot of sites, and surely, they are not all running IIS. Anyways. From what i understand, aps and php are pretty interchangable. At least, they were before asp.net. Who knows. Give it a shot and let us know how it works.
Have you played with php at all? If you havent jumped into asp that deep yet, maybe you could give php a shot, seeing as you alrady have the php modules for apache, and you dont have to go looking for them.
