[erlang-questions] Yaws with HTPPS authentication + HTTP

[Patrick]

What is the technique of user authentication with HTTPS with only
HTTPS for authentication and after authentication transferring user to
HTTP protocol? I know many sites use this(Gmail, Hotmail,... ) but how
to do it, esp. in Yaws?

I know that i cant have virtual servers on different ports on the same
IP(same computer) for HTTPS, will i need for that two physical
servers?

If anyone else had similar solution to problem can you pls. post small
tutorial? ;)

BR,
