I have Google App Engine running in HTTP (port tcp 80), which is a daemon based service it execute back-end some python instances. Now all that works over HTTP , TCP 80, and Google App Engine itself do not have any kind of HTTPS setup, it has to be organized externally.

Therefore, the biggest problem is now that how can i use stunnel to resolve this problem please?
I have already tried following setup and it does not work at all. 

1) if the user visit https://www.mysite.com then he hit stunnel accept=443 after that he is connected with connect=80 but user browser change into http:// instead of remaining in https:// . Which make the whole thing not working

$ uname -a
Linux server2 2.6.32-358.23.2.el6.x86_64 #1 SMP Wed Oct 16 18:37:12 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
$ cat /etc/stunnel/stunnel.conf
pid = /stunnel.pid

cert=/etc/stunnel/abyhu.crt
CAfile=/etc/stunnel/abyhu.ca
key=/etc/stunnel/abyhu.key

sslVersion = all
;socket = l:TCP_NODELAY=1
;socket = r:TCP_NODELAY=1
client=no

debug = 7
output = /var/log/stunnel.log

[SSL]
accept=443
connect=80
TIMEOUTclose = 0


My goal is: when user visit https://www.mysite.com it remain as https not become http:// then it is not solving the problem cause Google app engine do not have HTTPS



Thank you.

Best regards
