Static pages are those pages, which require no action at the server. The web server returns the page to the user without taking any special action. In these kinds of websites, no users interaction is available. These sites are used for display purpose only.

For example

if the user requests the user requests the static page by typing a URL www.iso.com/ home .html then the URL request is sent to the server which responds to the request without any specific action at the server.

➢ Dynamic Pages

These pages are created as a results of the user's action. An example of a dynamic pages is the page, which comes to the screen after user submits the form. The user fills in the text area selects the menus and check boxes present in the form. As soon as the user clicks on submit or post buttons on a form, the data from the form goes to the web server. The web server either passes the data to some application for further processing or posts the data to a database. After which the server displays the results to the user in the form of a HTML page.

➢ Directory Listing

The server generally creates these pages in response to queries. Whenever a user sends queries to the server without specifying the document name, directory listing is returned to the user in the form of a HTML page. The user can then visit the required file by clicking the desired option in the directory listing.

For example

The directory listing page is that page which is returned to the user as a result of search. The page contains the list of all possible pages containing desired information.
