Whta is difference between http vs https,
how to map the application if we want https in virtual directory

HTTP - Hyper text transfer protocol
HTTPS- HTTP with Socket Secure Layer (SSL), content are encrypted before tranmitting over the internet.

Which web server are you using Apache or IIS?

For IIS: right click on your virtual directory -> properties -> directory
security -> click Edit button under Secure Communications and select Require
secure channel (SSL). Any user accessing http://localhost/virt_dir will be
notified that he/she must use https://

You can use ASP to force SSL for that virtual directory pages.
