ColdFusion MX 6.1: Changed behavior for the name attribute: cfheader name="Content-Disposition" uses the default file character encoding to encode this header's value, so the name of a file can include characters in the character encoding used in the file.

|
| Usage
If you use this tag after the cfflush tag on a page, an error is thrown. |
