It may make more sense to create a new context 'user_uploaded_t' or some
such, and give the FTP server the access needed to write it, and the httpd
the needed read access.  That way, it gets "sandboxed" and even if it's
malicious code, nothing else can accidentally read/execute it, so your
system integrity is enhanced.

Depending on your paranoia level, you may or may not want to allow some
way for a process running in some user_t to un-sandbox the file.  It may be
sufficient to allow user_t to read it, as there probably shouldn't be any
automated processes running as user_t - with the implicit "the user is taking
responsibility for this"...
