Not "usename", but "usenameext". If you send such a filename, won't
MHonArc just create the file called "bin00001.htpasswd"?
Actually: "htp00001.htpasswd". The prefix is derived from the extension.
Hmmm, cannot think of any security problems off-hand. You still have a
problem with extension ambiguity and content-type vs extension
conflicts. I.e. There is no way to guarantee that the extension
provided matches the supplied content-type. For example, content-type
equals application/postscript but the filename given is "file.doc". Or
more likely, text/plain with a filename of "title.doc". Plus, not
everyone/system use extensions.
It is trivial for people to add "usenameext" if they want it. Keying
off the content-type is the proper way to do things. Deviations should
not be the default, and should only occur if the user requests it.
