Scripts for Dynamic Web Pages
• User input and Server Response• Similar to Windows programs• Need code to respond to user input
– Client Side Scripting
– Server Side Scripting
– Combination of above two approaches
11
Client Side Scripting
• HTML files and instruction files sent to client• Client Script • JavaScript• VBScript• Java Applets• Flash • . . .
12
Issues with Client Side Scripting
• Different browsers may interpret instructions in different ways
• Database is normally at server site
• Users could view source code
13
Server Side Scripting
• Instruction files are at server site • HTML files are generated according to user input• Only HTML files are sent to clients
14
Issues with Server Side Scripting
• Most computing is done at the server• Nothing will work when the server is down• More internet traffic• Powerful and expensive servers
15
Different Technologies forServer Side Scripting
• CGI (Common Gateway Interface)
• JSP (Java Server Pages)
• PHP (Personal Home Pages)
• ASP (Active Server Pages)
• ASP.NET • . . .
16
ASP.NET
• A server-side technology for creating dynamic web pages
• Client-side scripting is incorporated (e.g., to check input)• VB.NET or any other language
supported by .NET• Working with MS IIS
17
Internet Information Services (IIS)
• IIS waits and takes client requests
• IIS sends static HTML files to the clients
• IIS passes client requests to ASP.NET when needed
• ASP.NET generates dynamic web pages
• IIS sends dynamic web pages to clients
18
Windows Server Xray
• In domain ION• Our Web Sites• Individual student accounts
Each student has a Web site on Xray
19
Open Your Web Site on Xray
