Within this article we will show you how to deny traffic based on the HTTP User-Agent header.
This is achieved by configuring a header-field-group. Within this group we define a header string rule that matches any header that does not contain a defined string. This group is then associated to a content rule.
header-field-group deny-agent
header-field ua1 user-agent not-contain “spider”
content VIP-88.88.88.88
protocol tcp
vip address 88.88.88.88
port 80
url “/*”
header-field-rule deny-agent
add service server1
add service server2
