In the previous author, I will introduce you to the use of two very practical ASP built-in object Application and Session. Since the onstart of the two must be declared in the global.asa file, this article will give you the usage method of the global.asa file. In order to make everyone profess the knowledge you have learned, this article will also give an ASP CHAT program for reference.
Recently, many friends come to believe, why there is such a fault in the first two model programs. First of all, I want to declare everyone, these procedures are written by I have, after the "factory", after passing the test, there is no "counterfeit and shoddy product." :) Since the program is used to record customer information in the program, if you don't set up the cookie in your browser, the program will not function properly.
