This program will attempt to cover everything you need to know to work with the Common Gateway Interface in C#, including reading the input of POSTs and GETs. Although this sounds like a lofty goal, CGI is actually quite easy to get into and gains most of its power from its simplicity. Despite that simplicity, I ve labeled this as "Intermediate" because in order to take total advantage of CGI, I had to slip in some intermediate things, such as threading. Threading is presented in its most straight forward of terms, however, and only briefly utilized, so don t fret. Even if you have never worked with threading in C# before, I believe you will not have trouble with that part or any other sections that earned the "Intermediate" status.-This program will attempt to cover everything you need to know to work with the Common Gateway Interface in C#, including reading the input of POSTs and GETs.
