A website is a container for web applications, and you can access it through one or more unique bindings. A website binding is the combination of an IP address, a port, and a host header on which the web server listens for requests made to that website. Website bindings use the HTTP or HTTPS protocols and you can view bindings created for your account in HostPilot Control Panel on the Web Server > Server Information page.
The HTTP and HTTPS bindings are created for each domain (host header). The FTP binding is not shown on your Server Information page because in IIS 7 all sites share one FTP binding. By default, the FTP service works for all sites and FTP access is managed via the FTP Access tab on the Web Server > Access Permissions page.
