Here are two methods I have used in practice. Method 1: use cookies for interaction. There are three files in total: index.htm, action.php, and main.htm. the original principle is that the front page main.htm and the background action. php use the page box to create the front page and
Maintaining interaction between CGI pages in the background is always a problem. Here we will introduce two
.

Method 1: use cookies for interaction. There are three files in total:
Index.htm,action.php, main.htm

Index.htm is organized to set the page width of action. php to 0.
Impact display. Action.php puts the information into cookie, and main.htm reads the information
Cookie. In main.htm, you can also re-read action. php
To control the CGI program in the background.
