To install your SSL certificate, you will need to do the following:
Save your SSL certificate as gs_ssl_certificate.crt.
Open IIS and Select Key/Install Key certificate and select the file you just saved. You will be asked to give a password. If you don't remember having given one, leave it empty.
If the certificate matches with the keys you created, it will be installed, and IIS will ask you whether you want to bind it to a specific IP address or not.
Force secure connection:
Go to the Internet Service Manager.
Right-click on the directory you want to SSL secure. Select Directory Security.
Click on the Require Secure Channel to make sure the pages can only be seen via a https:// connection.
Make sure all referring pages use the https:// prefix to send users to this page!
