Network simulator : HTTP server and navigator

This is the "parameter setting" screen of a HTTP server:

Parameter setting of a HTTP server

The publication folder (document root) cannot be changed.
The protocol and the number of the port which the stations listens to tell you how you can reach the service.
The "automatic starting" option requires the service to be launched at the same time as the hosting station.
You can use the "Information of connection to a DBMS" option to set the protocol and the number of the port to be used when the HTTP server has to connect to a database during the execution of a PHP script.

When a HTTP server is installed, eight files are automatically created in the c:\www folder of its hard disk.

"f001.html" and "f002.html" display a simple message. This message can be changed.
"f003.html" illustrates the use of JavaScript to display a user message. This message can also be changed.
"f004.php" illustrates the use of PHP to display a user message. This message can also be changed.
"f005.html" illustrates the setting up of a hypertext link. The page pointed by this link can be changed.
"f006.php" illustrates the execution of a PHP page which connects to a DBMS to count the number of lines in a table. This page has to be parameterized in order to indicate the information related to the connection to the DBMS, as well as the table's name.
"f007.html" displays a HTML form, performs a validity check in JavaScript, and calls the "f008.php" page when the form is submitted.
"f008.php", which is triggered by the "f007.html" page, carries out an extraction of data to build a HTML flow in an active way. This page must be parameterized to indicate the information related to the connection to the DBMS, as well as the table's name.

In order to set the parameters of these pages, you can use the "hard disk" option in the pop-up menu of the server's station (see File Edition).

When you set the parameters of a navigator, you can change only the protocol that is used.
