I have a ROI/RFM tracking program built in classic ASP and ready to be installed on our website. But now we are converting to .NET (which I am for). I was going to tag this program onto every needed page via server-side include. With .NET the way to essentially do an include is with a User Control, which is great but here's my dilemma... We're temporarily (6 mo.'s or so) keeping our shopping cart in classic ASP so I need this program to be compatible between both .NET _AND_ classic ASP.<BR><BR>How do I do a thing like this? Should I just have two versions of the same program (.NET / ASP) or is there a better, more efficient way?<BR><BR>Thanks so much!
