Differences between application and session.

Posted By :Shashi Ray     Posted Date :November 27, 2008    Points :10   Category :ASP.Net 
The session object maintains state on a per client basis whereas the application object is on a per application basis and is consistent across all client requests.

You can also find related Interview Question to Differences between application and session.  below: 

what is different between session and application

  
session is a object that store information between http request for a paticular user.
->But application object are global for each user (More...)

Which typically consumes more memory: application state or session state?

  
Session state tends to use much more memory than application state, because copies of all variables are stored for each user. (More...)

Which might not work if a user has disabled cookies in his or her Web browser: application state or session state?

  
Session state, by default, won't work if a Web browser that supports cookies has cookies disabled. Application state isn't user-specific, though, and doesn't need to be tracked in cookies. Therefore, application state works regardless of cookies. (More...)

What is the difference between Application caching and session objects?

  
Session A session is the time for which a particular user interacts with a web application. During a session the unique identity of the user is maintained internally. A session ends if there is a session timeout or user ends sessionby logging out.Sessions may change from user to user.

Cache Caching can be used to temporarily store page output or application data either on the client or on the server, which can then be re-used to satisfy subsequent requests and thus avoid the overhead of re-creating the same information.Caching is particularly suitable when you expect to Cache will be applicable to the entire application through out it's life cycle return the same information in the same format for many different requests.

Application Its nothing but similar to Session with a bit difference that is Session objects have scope within a particular session while application objects having scope within entire application. Application are accessible only from code running within the context of the originating application. Other applications running on the system cannot access or modify the values.

what is session ,cache, cookie, application memory timeout?

  

Session timeout: 20 min
Cache timeout: duration we have to specify.
Cookie: for in memory cookie till browser opened
For persistent cookie timeout is till expires property's time .
Application memory timeout: till appdomain exist (More...)

Differences between Windows And Console Application?

What do you mean by SESSION and APPLICATION object in asp.net?

  
Session object store information between HTTP requests for a individual user and application object are global across all users. (More...)

What do ypu mean by SESSION and APPLICATION object ?

  
Session object store information between HTTP requests for a particular user, while application object are global across users. (More...)

What is the difference between ViewState,Application and Session of a Page?

  
View State:

- View state is maintained in page level only.
- View state of one page is not visible in another page.
- View state information stored in client only.
- View state persist the values of particular page in the client (browser) when post back operation done.
- View state used to persist page-instance-specific data. (Read more)

Session State:

- Session state is maintained in session level.
- Session state value is available in all pages within a user session.
- Session state information stored in server.
- Session state persist the data of particular user in the server. This data available till user close the browser or session time completes.
- Session state used to persist the user-specific data on the server side. (Read more)

Application State

ApplicationState is a variable you can store values in during the life off the application (may get cycled periodically, and without your knowledge) (used less-frequently)


Usage

- If you want to access the information on different web pages, you can use SessionState
- If you want to access from the same page, then you can use Viewstate
-Application State it's global, for all users

Security

Session state provides more security when compared with view state as the data value is stored in server side (More...)

What is Application Domain?

  
The primary purpose of the AppDomain is to isolate an application from other applications. Win32 processes provide isolation by having distinct memory address spaces. This is effective, but it is expensive and doesn't scale well. The .NET runtime enforces AppDomain isolation by keeping control over the use of memory - all memory in the AppDomain is managed by the .NET runtime, so the runtime can ensure that AppDomains do not access each other's memory.
Objects in different application domains communicate either by transporting copies of objects across application domain boundaries, or by using a proxy to exchange messages.
MarshalByRefObject is the base class for objects that communicate across application domain boundaries by exchanging messages using a proxy. Objects that do not inherit from MarshalByRefObject are implicitly marshal by value. When a remote application references a marshal by value object, a copy of the object is passed across application domain boundaries. (More...)

What is the differences between delegates and interfaces?

  
Interfaces carry semantics, and when a programmer implements an interface, he is typically well aware of that semantics. When you try to invoke a particular method via an interface, you can be fairly certain that if you succeed, the semantics of that method is what you expect. For that reason, using interfaces is essentially doing a check for semantic correctness on some level.


Delegates, on the other hand, by only verifying the method signature, make the programmer responsible for ensuring that the semantics of the method is compatible. The semantics may cover not only the meaning of the arguments and return value (some times even the order of the arguments if they are of the same type), the ranges of the arguments, but also an invocation order when multiple methods are concerned. Hence, in a sufficiently large program there is plenty of margin to make an error when different programmers are not forced to comply with a uniform semantics (as they would be if interfaces were used).

I have written an assembly that I want to use in more than one application. Where do I deploy it?

  
Assemblies that are to be used by multiple applications (for example, shared assemblies) are deployed to the global assembly cache. In the prerelease and Beta builds, use the /i option to the Alink SDK tool to install an assembly into the cache:
al /i:myDll.dll
A future version of the Windows Installer will be able to install assemblies into the global assembly cache. (More...)
