I have spent a lot of time over the last couple of days and weeks working with ASP. I have never ventured into this area until recently due to some changes that I wanted to make to my web site. I used ASP to restructure one section, (Tips and Tricks), on my website around and introduced two new sections, (Command and System Variable References). I found a series of articles that were very useful when trying to figure out which direction to take for the redesign, ASP or ASP .Net. Of course, part of the decision is based on what is on the web server you are using. Most if not a majority of the web servers are most likely running the .Net framework to allow for the use of ASP .Net.
Hope you find the information beneficial and educational.
