Default Page

When you type the url in the browser's address bar, for example:

http://mcb2300

the Web server sends the content of index.htm web page. This is the default page, which is opened, when no filename is specified in the url. If you enter the complete url with a filename, for example:

http://mcb2300/ad.htm

then the Web server tries to open this page.

The default page index.htm is a static page. This means the content of this page is stored on Web server and sent unmodified to the web client on request. Usually this page contains links to other static or dynamic pages on the Web server.

Sometimes a dynamic page is preferred as a default web page. Embedded Web server implicitly supports also this option. When a web browser requests a default web page, the web server tries to open index.htm as default web page. If this page does not exist, Web server in the next step tries to open index.cgi as a default page. If this page is also not existing, then the Web server responds with Error 404 - Not Found.

 

  • If you want to use a dynamic default page, then the file index.htm must not exist on the Web server.
