Fortinet 262 FortiWeb 5.0 Patch 6 Administration Guide
8. Repeat the previous steps for each web server that you want to add to the server farm.
9. Click OK.
10.To apply the server farm, select it within a server policy.
If the server farm will be used with a server policy whose Deployment Mode is one of the
content routing modes, place the web server that you want to be the failover first in the list of
web servers in the server farm. In content routing, each server in the server farm might not
host identical web services. If a web server is unresponsive to the server health check, the
FortiWeb appliance will forward subsequent connections to the first web server in the server
farm, which will be considered to be the failover. Make sure the first web server can act as
a backup for all other servers in the server farm.
To monitor members of the server farm for responsiveness, configure a server health check
for use with the server farm. For details, see “Configuring server up/down checks” on
page 254.

Routing based upon URL or “Host:” name
Instead of forwarding requests to back-end servers based upon load or connection distribution
at the TCP/IP layers, you can forward them based upon headers in the HTTP layer. This can be
useful if specific web applications, functions, or host names are divided, and each served only
by a specific web server on the back end — that is, each web server in the server farm is not
identical, but is specialized, such as:
• 192.168.0.1 — Hosts the web site and blog
•192.168.0.2 — Hosts movie clips and multimedia
• 192.168.0.3 — Hosts the shopping cart
Weight If the server farm will be used with the weighted round-robin
load-balancing algorithm in the policy, type the numerical weight of
the web server to be used when proportionately distributing TCP
connections.
Web servers with a greater weight will received a greater proportion of
connections.
This can be useful if, for example, some servers in the server farm are
more powerful, or if a server could be already receiving fewer or more
connections due to its role in multiple web sites.

HTTP Content
Routing
Select the name of an existing HTTP header-based routing policy, if
any, that will be used to route requests to this web server in the server
farm. See “Routing based upon URL or “Host:” name” on page 262.
This field appears only if Type is HTTP Content Routing.
