Usage

The client variable must exist before using this function. The ClientManagement attribute of cfapplication tag must have been set to "Yes" for this template.

Note

If you concatenate string elements to form the name parameter, you can improve performance using CFSET instead.

For example:

    <cfset "myVar#i#" = myVal>

is faster than:

    SetVariable("myVar" & i, myVal)
