ColdFusion comments have a similar format to HTML comments. However, they use three dash characters instead of two; for example:
<!--- This is a ColdFusion Comment. Browsers do not receive it. --->
The ColdFusion Server removes all ColdFusion comments from the page before returning it to the web server. As a result, the page that a user browser receives does not include the comment, and users cannot see it even if they view the page source.
You can embed CFML comments in begin tags (not just tag bodies), functions calls, and variable text in pound signs. ColdFusion ignores the text in comments such as the following:
<cfset MyVar = var1 <!--- & var2 --->>
<cfoutput>#Dateformat(now() <!---, "dddd, mmmm yyyy" --->)#</cfoutput>
This technique can be useful if you want to temporarily comment out parts of expressions or optional attributes or arguments.
Note: You cannot embed comments inside a tag names or function name, such as <cf_My<!--- New --->CustomTag>. You also cannot embed comments inside strings, as in the following example: IsDefined("My<!--- New --->Variable").
