A group of ASP files may be called an application on the Web . Some purpose can be achieved when the ASP file work together.In ASP ,the Application object is used to tie these files together.

For storing and accessing variables from any page, just like the Session object,the Application object is used . The difference is that in Sessions there is one Session object for EACH user while ALL users share one Application object .

In the Particular application (like database connection information),the Application object should hold information that will be used by many pages . This means it is possible access the information from any page. In an Application object , you can change the information in one place and the changes will automatically be reflected on all pages.

In the application,application variables can be accessed and changed by any page .

You can create Application variables using "Global.asa" like this:

In the example above we have created two Application variables: "vartime" and "users".

Application variables can be accessed like this:

All application variables wil be stored in Contents collection .To see what's stored in it ,you can loop through the Contents collection, :

You can use the Count property if you do not know the number of items in the Contents collection, :

To see the values of all objects stored in the Application object,you can loop through the StaticObjects collection :

• Using "Lock" method,you can lock an application

• The users cannot change the Application variables(other than the one currently accessing it),when an application is locked .

• Using "Unlock" method,you can unlock an application

• This method is used to remove the lock from the Application variable:
