1) read the file to a variable.
2) prepend the data to the variable data
3) write the variable data to a new temp file
4) delete the original file
5) rename the temp file to the name of the original file
This is inelegant and I'd think slow. It might be OK if you weren't hitting it much, but under load I'd think it would be a bad idea.

Thanks Matt.
Is there anyway to "append" information to the top of a file. I'm doing it to the bottom, but it would be nice if I can get a certain line on the very top.

Try this:
<cfset a="<cfoutput>123</cfoutput>">
<cfoutput>#a#</cfoutput>
View the page's HTML. You should see the cfoutput tags in there - at least I
do on 6.1.

Since I suggested using CFscript its my bad. If you were outside of CFSCRIPT
then you would need to escape <>.
