I followed this tutorial install SSL
http://guides.jlbn.net/setssl/setssl1.html

I setup up to localhost

after the configuration, I able to access HTTPS (https:// localhost/)
however, when I want to access to HTTP (http:// localhost/)

It display

Bad Request

Your browser sent a request that this server could not understand.
Reason: You're speaking plain HTTP to an SSL-enabled server port.
Instead use the HTTPS scheme to access this URL, please. Hint:
https:// localhost/

How do I make both HTTP and HTTPS works?

I read SSL – how to make both http and https work
I also add VirtualHost for 80 and 443 to httpd.conf. But no luck.

Please help.
Thanks
