CFML Language Reference

Lock the application scope. In the CFLOCK tag, indicate scope by
specifying "APPLICATION" as the value of the SCOPE attribute.

Lock the server scope. In the CFLOCK tag, indicate the scope by specifying
"SERVER" as the value of the SCOPE attribute.

Unlock the server scope.

Unlock the application scope.

Unlock the session scope.

Note

You can take out any pair of lock/unlock steps if you do not need to lock a
particular scope. For example, you can take out Steps 3 and 4 if you do
not need to lock the server scope. Similar rules apply for named locks.

For complete usage information on CFLOCK, see Developing Web Applications with
ColdFusion.

Example

<!-------------------------------------------------------------
This example shows how CFLOCK can be used to guarantee the
consistency of data updates to variables in the Application,

Server, and Session scopes.
You should copy the following code into an Application.cfm

file in the snippets directory.

<H3>CFAPPLICATION Example</H3>

<P>CFAPPLICATION defines scoping for a ColdFusion application and
enables or disables the storing of application and/or session
variables. This tag is placed in a special file called
Application.cfm that is run before any other CF template in a
directory where the Application.cfm file appears.</P>

<!----------------------------------------------------------------------

Initialize the session and application variables that will be
used by E-Turtleneck. Use the session scope for the session
variables.
