ASP.NET Request-Processing Architecture

• ASP.NET request data flow

Bina Nusantara References: ProASP.NET 3.5 Server Controls and AJAX Components(Rob Cameron and Dale Michalk, 2008)

ASP.NET Request-Processing Architecture (Continue…)

• ASP.NET request processing classes


ASP.NET and Server-Side State Management

• The Context Object


Property Description

Application Provides server-side state management for all clients of the web Application

ApplicationInstance

Reference controls the execution process of the ASP.NET web request

Cache Provides access to the server-side cache in ASP.NET

Error Provides access to the error exceptions that occur during ASP.NET execution

Items Key/value pair collection used to pass information between the components in a request

Request Contains information from the client request, including browser type, cookies, and values encoded in form and URL query string collections

Response Key/value pair collection used to pass information between therequesting components

Server Provides utilities including Server.Transfer, Server.HtmlEncode, and Server.MapPath

Session State collection maintained on behalf of a web application user

Trace Debugging utility for writing to the trace output of the web form

User Makes security information available when a user is authenticated

ASP.NET and Client-Side State Management

Caching Application Pages and Data

• Page Output– Varying by Parameter (QueryString)– Varying by Control

• Partial Page Caching– Post-Cache Substitution

Bina Nusantara References: ASP.NET 3.5 Unleashed (Stephen Walther, 2008), Pro ASP.NET for SQL Server (Brennan Stehling, 2007)

Caching Application Pages and Data (Continue…)

– Post-Cache Substitution (continue…)

– Advantages using WriteSubstitution() method• Can be method of other class• Can be use in custom control



– Caching with user control



• DataSource Caching

• Data Caching



• Data Caching (continue…)


Optimize Application and Session State Management

• Application State– This is information that applies to all clients of the Web

application. This information is shared by, and managed for, multiple clients.

• Session State– This is information that applies to a specific client

session. You manage this information for individual clients.

• Setting Session State

Bina Nusantara References: Performance Tuning and Optimizing ASP.NET Applications (Jeffrey Hasan and Kenneth Tu, 2003)

Optimize Application and Session State Management (Continue…)

• Setting Session State (continue…)


Mode Description

InProc (default) which stores session state in memory on the Web server

StateServer stores session state in a separate process called the ASP.NET state service

SQLServer stores session state in a SQL Server database

Custom enables to specify a custom storage provider

Off disables session stateCookieless

modeDescription

AutoDetect ASP.NET determines whether the requesting browser or device supports cookies

UseCookies Cookies persist user data, regardless of whether the browser or device supports cookies

UseDeviceProfile

ASP.NET determines whether to use cookies based on the HttpBrowserCapabilities setting

UseUri The calling feature uses the query string to store an identifier, regardless of whether the browser or device supports cookies

Optimize Application and Session State Management (Continue…)

• Choosing the right ASP.NET State Management Option– Session State:

• Does the application require centralized session state management, or can it be managed on individual Web servers?

• Does the application require cookie-based or cookieless session state?

• What kind of information needs to be stored?• Does the application really need a Session object for all

information?

– Application State:• Does the application require permanent application state? • Does the application require transient application state?• How frequently will stored items be updated?• Does the client need direct access to the item?


That’s AllThank You for the Attention
