Cfcontent/cfheader doesn't support file pause/resume.

Question

I'm testing the possibility of using cfcontent to serve my file downloads for security purposes. Files in the web root seem to be open to all on the web but I can use cfcontent to serve files from an otherwise unaccessable directory. The downloads are working great but they cannot be paused or resumed in a download manager. Am I doing something wrong or what?
Here's my code;
<cfif isdefined('url.downloadpath')>
    <cfheader name="Content-Disposition" value="attachment; filename=#replace(url.filename,' ','_','all')#">
    <cfheader name="Content-Length" value="#url.filesize#">
    <cfheader name="Content-Type" value="application/octet-stream">
    <cfheader name="Content-Location" value="./?#query_string#">
    <cfcontent type="application/octet-stream" file='#url.downloadpath##url.filename#'>
    <cflocation addtoken="no" url="./?#left(query_string,find('&downloadpath')-1#">
</cfif>
Thanks,
Jon

Where did you learn that turning the iPod off and later turning it on takes more power from the battery than leaving it in sleep mode? I'm not saying that you are wrong, just interested where this info came from.
