  1. Server Side Scripting Dawn Pedersen

  2. What is Server-Side Scripting? • Client-side scripting is about "programming" the behavior of the browser. • Server-side scripting is about "programming" the behavior of the server.

  3. What is Server-Side Scripting? • Normally when a browser requests an HTML file, the server immediately returns the file. • However, if the file contains a server-side script, the script inside the HTML file is executed by the server before the file is returned to the browser as plain HTML.

  4. What Can Server Scripts Do? • Dynamically edit, change or add any content to a Web page

  5. What Can Server Scripts Do? • Respond to user queries or data submitted from HTML forms

  6. What Can Server Scripts Do? • Access any data or databases and return the results to a browser

  7. What Can Server Scripts Do? • Customize a Web page to make it more useful for individual users

  8. What Can Server Scripts Do? • Allow you to use and reuse code snippets called “includes”. • The includes are saved and edited in another file.

  9. Types of Server Scripts • Active Server Pages (ASP) was developed my Microsoft for creating dynamically-generated web pages. • First released in 1998. • Runs on Windows Server. • Succeeded by ASP.NET in 2002. • Files end in .asp (for ASP) or .aspx (for ASP.NET).

  10. Types of Server Scripts • PHP: Hypertext Preprocessor (PHP) is a widely used, general-purpose scripting language. • Created in 1995 and originally stood for personal home page. • Can be interpreted by any web server with a PHP processor module. • Most commonly run on Apache web server software. • Files typically end in .php.

  11. Types of Server Scripts • Perl • JSP • Ruby • ColdFusion • Python • CGI

  12. Advantages of Server-Side Scripts • Does not require the user to download plugins. • Load times are generally faster than client-side scripting.

  13. Advantages of Server-Side Scripts • You can create a single website template for the entire website; each new dynamic page you create will automatically use it. • You can configure a site to use a content management system, which simplifies the editing, publishing, adding of images, and creation of web applications.

  14. Advantages of Server-Side Scripts • Your scripts are hidden from view. Users only see the HTML output, even when they view the source.

  15. Disadvantage of Server-Side Scripts • Server-side scripts can be used by attackers to gain access to the server. • Because the scripts often respond to URL input, changing the URL to something that exploits a security hole can give the user server access. • To combat such attacks, system administrators need to keep all server-side scripts updated to their latest secure versions and use a firewall.

  16. Who Creates the Scripts? • Both client-side and server-side scripts are generally written by web developers rather than web designers. • However, a solid understanding of the basics of both can make a web designer more powerful and able to generate a larger income.
