The only reason it doesn't apply to paste.httpserver is because it
doesn't have a URL mapping system of it's own. That is, you host a
single WSGI application at the root of the server. Any server which
allows hosting of a WSGI application at a sub URL will have such
issues. Specifically, the details of the sub URL are worked out by the
server, be it by mapping a URL to the file system or through matching
to a configuration parameter in a server configuration file.
