The document discusses key concepts in ASP.NET including server-side scripting, client-side components like JavaScript and CSS, separating design from code using rich web forms, the page lifecycle with events like load and render, view state for storing page data on the client, session state for storing objects during a user's session, and the difference between websites and web applications.

2.  Simply Server side language
 Simplified page development model
 Modular, well-factored, extensible architecture
 Superior debugging and tracing support
 Compiled, not interpreted
 Rich caching support
 Web farm scalable session state
 Automatically detects and recovers from errors

4.  Client Side Scripting
 Server Side Scripting
 HTML
 JavaScript
 CSS
 JQuery
 Ajax
 XML

5.  Separate Code & Design
 Rich Web Forms
 Drag & Drop Design
 Like WinForms

6.  Page Directive
 Server side code
 Form
 Normal HTML Structure
 Server Controls

8.  Post Back
 communicates back to the server
 View State
 state stored in a hidden field on the page
 transported to the client and back to the server,
 Is not stored on the server

9.  Session State
 allows the state of objects (serializable) to be stored
for a single session (lifetime of the user’s browser or
specific timeout)
 Application State
 allows the state of objects (serializable) to be stored
for the application across different sessions.

10.  Template to Other pages

11.  Web Site
 Don’t use this, here for compatibility only
 Each page is dynamically loaded into memory
 Slow on first load after deployment
 No need to recompile for code change

12.  Web Application
 Recommended
 Compiles all pages into one DLL
 Faster on first load after deployment
 Must recompile whole site for code change
