|CoverYourASP --> Server Side Includes|
|SSI allows me to suck in common code from files into my pages. You'll see in the examples below how I have a common Init () function to output the common HTML <head>, a common Header () function to output the same header at the top of each page, and a common Footer () to output the same bottom of page.|
I use the same template for each page, as shown below. This is literally my source code, and the file I use when I create any new page on the site. I load this, then start typing in the new code...
Please spread the word by recommending my site to your friends and colleagues!
The syntax of the include should be familiar to any C/C++ programmers, except for the "file" part. You can use "file" or "virtual". Use the file keyword to indicate a relative path, and the virtual keyword to indicate an absolute path beginning with a virtual directory.
Note: Regardless of Microsoft's recommendations to use an .inc extension for include files, DON'T DO IT. Anyone can view the contents of these files if they know the name, and you could "give away" potentially fatal information. The golden rule is: Always use an .asp extension.
The effect of this #include line, of course, is to suck in the contents of the referenced file as if it was there all along!
First, let's look at the Startup.asp file that contains all the standard page elements:

Init.aspInit.asp initializes the page, including performing once-a-day tasks, redirecting spiders to special pages, outputting the HTML <HEAD> and relevant META tags and incrementing the article counter in the database.

Header.aspThis file outputs the header at the top of every page on the site. That's the beauty of SSI - change this one file and every page gets the new header automatically.
