After using HFS for a while I've come to miss a "function" that would be very handy for me at least. Say I want to stop sharing a file, but at the same time I want to keep the server up. Instead of getting an error message, it would be nice if I could redirect them to another file of my choice.
Example
I have a file called file01.exe that I'm sharing. I don't want to share it anymore, so right clicking on the file could give me the option to "stop sharing and redirect". In the option for that I could just point to another file/url of my choice. Say a "info.htm" where I maybe explain why the file is no longer there and maybe even re-direct to an off-site url that holds a mirror of the file.
