Load Balancing
The strategy that the web proxy uses to load balance requests between
multiple upstream proxies. Choose from:
multiple upstream proxies. Choose from:
•
None (failover). The Web Proxy directs transactions to one external
proxy in the group. It tries to connect to the proxies in the order they are
listed. If one proxy cannot be reached, the Web Proxy attempts to
connect to the next one in the list.
proxy in the group. It tries to connect to the proxies in the order they are
listed. If one proxy cannot be reached, the Web Proxy attempts to
connect to the next one in the list.
•
Fewest connections. The Web Proxy keeps track of how many active
requests are with the different proxies in the group and it directs a
transaction to the proxy currently servicing the fewest number of
connections.

•
Hash based. Least recently used. The Web Proxy directs a transaction
to the proxy that least recently received a transaction if all proxies are
currently active. This setting is similar to round robin except the Web
Proxy also takes into account transactions a proxy has received by being
a member in a different proxy group. That is, if a proxy is listed in
multiple proxy groups, the “least recently used” option is less likely to
overburden that proxy.
