I hate to say it (because I hate to hear it), but we can't really help you unless we see your code.
type = "application/epub+zip"
file = "#desti#"
deleteFile = "No"
Try adding CFHEADER to the mix.
<cfheader name="Content-Disposition" value="attachment; filename=#_PUT_FILENAME_HERE_#">
<cfcontent type="application/epub+zip" file="#desti#" deletefile="no"> <!--- Are you sure that epub+zip is correct?? --->
This is the solution! thank you very much !
epub+zip is good for epub !
But, I know not group items into a epub ;-(((((
Glad to hear that it's working as you expect. Could you, please, mark my answer as correct, so that future searchers can find it?
I moved the "Correct Answer" to the one that actually answered the question - for posterity.
