James,
SP6a breaks exactly this functionality in IIS that you describe -- using a different
file extension at the end of a URL will screw up CFM processing.
The trick I learned here, from Dave Watts I believe, is to use the following line
right before you deliver the file to be downloaded via CFCONTENT:
<CFHEADER NAME="Content-Disposition" VALUE="inline; filename=filename.pdf">
This will make the browser properly think it's about to download a file named
"filename.pdf," regardless of the link that was originally clicked. Works great in NN
and IE.
The other fix is to not use IIS or SP6/a :)
HTH,
