Syntax
    <cfexit
       method = "method">

Usage If this tag is encountered outside the context of a custom tag, for example in the base page or an included page, it executes in the same way as cfabort. The cfexit tag can help simplify error checking and validation logic in custom tags. The cfexit tag function depends on its location and execution mode:
exitTag | Base page | Terminate processing
| Execution mode = Start | Continue after end tag
| Execution mode = End | Continue after end tag
exitTemplate | Base page | Terminate processing
| Execution mode = Start | Continue from first child in body
| Execution mode = End | Continue after end tag
loop | Base page | Error
| Execution mode = Start | Error
| Execution mode = End | Continue from first child in body
Example
    <h3>cfexit Example</h3>
    <p>cfexit can be used to abort the processing of the currently executing
    CFML custom tag. Execution resumes following the invocation of
    the custom tag in the page that called the tag.
    <h3>Usage of cfexit</h3>
    <p>cfexit is used primarily to perform a conditional stop of processing
    inside a custom tag. cfexit returns control to the page that
    called that custom tag, or in the case of a tag called by another
    tag, to the calling tag.

    <!--- cfexit can be used within a CFML custom tag, as follows: --->
    <!--- Place this code (uncomment the appropriate sections) within the
    customtags directory. --->

    <!--- MyCustomTag.cfm --->
    <!--- This simple custom tag checks for the existence.
    of myValue1 and myValue2. If they are both defined,
    the tag adds them and returns the result to the calling
    page in the variable "result". If either or both of the
    expected attribute variables is not present, an error message
    is generated, and cfexit returns control to the
    calling page. --->

    <!--- <cfif NOT IsDefined("attributes.myValue2")>
             <cfset caller.result = "Value2 is not defined">
             <cfexit method = "exitTag">
        <cfelseif NOT IsDefined("attributes.myValue1")>
             <cfset caller.result = "Value1 is not defined">
             <cfexit method = "exitTag">
        <cfelse>
              <cfset value1 = attributes.myValue1>
              <cfset value2 = attributes.myValue2>
             <cfset caller.result = value1 + value2>
        </cfif> --->
    <!--- End MyCustomTag.cfm --->

    <!--- Place this code within your page --->

    <!--- <p>The call to the custom tag, and then the result:
    <CF_myCustomTag
          myvalue2 = 4>
    <cfoutput>#result#</cfoutput> --->
    <p>If cfexit is used outside a custom tag, it functions like a cfabort.
    For example, the text after this message is not processed:
    <cfexit>
    <p>This text is not executed because of the cfexit tag above it.
