var total=x+y;
return total;
}

<CFSAVECONTENT>
• <CFSAVECONTENT> caches the HTML output of all CFML constructs within the tags
• Enables the caching of specified sections of a page for later recall
• Similar to <CFA_GeneratedContentCache> in Allaire Spectra and other tags currently available on the Allaire Tag Gallery
• Operates faster than the tags on the Gallery
• NOTE: All output is suppressed within the tags

<CFFLUSH>
• Flushes the current ColdFusion output buffer
• Use it to start sending output to the web client before the page has fully completed processing
• After a <CFFLUSH> has executed, the following tags will generate an exception:
• CFCONTENT
• CFCOOKIE
• CFFORM
• CFHEADER
• CFHTMLHEAD
• CFLOCATION
