HTTP/HTTPS Server Load Balancing
The Hypertext Transfer Protocol (HTTP) is a Layer 7 request-response protocol standard that lets you
communicate between the client and the server. The client sends HTTP requests to the server, which
sends messages, or responses, back to the client. The default port used for HTTP is 80, but it also
can be used with other non-standard ports.
HTTPS, or HTTP Secure, combines HTTP with the SSL/TLS protocol, thereby enabling data encryption
and secure server identification. The default port used for HTTPS is 443 but it also can be used with
other non-standard ports.
Alteon enables you to load balance HTTP/HTTPS traffic.
Note: For a list of well-known ports identified by Alteon, see Supported Services and Applications,
page 175.
