HTTP header rules
HTTP header rules cause the Brocade Virtual ADX to make a load-balancing decision based on the
contents of an HTTP header field in an incoming packet.
In an Layer 7 content switching configuration, you can configure rules for the following HTTP header
fields: Connection, Transfer-Encoding, Content-Length, Host, Cookie, Pragma, and Cache-Control,
as well as up to 10 other HTTP header fields.
Table 24 lists the HTTP header rules available for Layer 7 content switching.
