forward( )

Determines forwarding behavior.

There is a box-wide configuration setting (

config>forwarding>sequence

) for the default forwarding 

failover sequence. The 

forward( )

 property is used to override the default forwarding failover 

sequence with a specific list of host and/or group aliases. The list of aliases might contain the special 
token default, which expands to include the default forward failover sequence defined in 
configuration. 

Duplication is allowed in the specified alias list only in the case where a host or group named in the 
default failover sequence is also named explicitly in the alias_list.

In addition, there is a box-wide configuration setting (

config>forwarding>failure-mode

) for the 

default forward failure mode. The 

forward.fail_open( )

 property overrides the configured default.

forward(alias_list|no)

where:

•

—Forward this request through the specified alias list, which might refer to both 

forward hosts and groups. The ProxySG attempts to forward this request through the specified 
hosts or groups, in the order specified by the list. It proceeds to the next alias as necessary when 
the current host or group is down, as determined by health checks.

•

no

—Do not forward this request through a forwarding host. A SOCKS gateway or ICP host may 

still be used, depending on those properties. If neither are set, the request is sent directly to the 
origin server. Note that 

no

 overrides the default sequence defined in configuration.

The default value is
