Selecting servers based on load-balancing metric instances

A signal-bearing medium encoded with instructions, wherein the instructions when executed comprise:

• receiving a current request from a client, wherein the current request is directed to a page;
• determining whether a first session associated with the current request already exists, wherein the determining further comprises determining whether the current request is dependent on a previous request;
• if the determining is false, deciding whether the request will result in creation of a second session;
• if the deciding is true, selecting a first server based on a load-balancing metric instance associated with the page, and sending the current request to the first server;
• and
• if the determining is true, sending the current request to a second server that is associated with the first session.

A method for configuring a computer, comprising:

• configuring the computer to receive a current request from a client, wherein the current request is directed to a page;
• configuring the computer to determine whether a first session associated with the current request already exists, wherein the configuring the computer to determine further comprises configuring the computer to determine whether the current request is dependent on a previous request;
• configuring the computer to, if the determining is false, decide whether the request will result in creation of a second session, wherein the current request will result in the creation of a second session if a previous request was directed to the page and the previous request created a third session;
• configuring the computer to, if the deciding is true, select a first server based on a load-balancing metric instance associated with the page, and sending the current request to the first server;
• and
• configuring the computer to, if the determining is true, send the current request to a second server that is associated with the first session.
