Set the real server group metric to minmisses.
This setting helps minimize Web cache misses in the event real servers fail or are taken out of
service:
>> Real server group 1# metric minmisses

Verify that server processing is disabled on the ports supporting application redirection.

processing is used only with SLB. To disable server processing on the port, use the commands
on the /cfg/slb/port menu, as described in Chapter 8 of the Web OS Command Refer-
ence.

Create a filter that will intercept and redirect all client HTTP requests.
The filter must be able to intercept all TCP traffic for the HTTP destination port and must redi-
rect it to the proper port on the real server group:
>> SLB port 6# /cfg/slb/filt 2
>> Filter 2# sip any
>> Filter 2# dip any
>> Filter 2# proto tcp
>> Filter 2# sport any
>> Filter 2# dport http
>> Filter 2# action redir
>> Filter 2# rport http
>> Filter 2# group 1
>> Filter 2# ena
The rport parameter must be configured whenever TCP/UDP protocol traffic is redirected.
The rport parameter defines the real server TCP or UDP port to which redirected traffic will
be sent. The port defined by the rport parameter is used when performing Layer 4 health
checks of TCP services.
Also, if NAT and proxy addresses are used on the Web switch (see
rport parameter must be configured for all application redirection filters. Take care to use
the proper port designation with rport: if the transparent proxy operation resides on the host,
the well-known port (80 or "http") is probably required. If the transparent proxy occurs on the
Web switch, make sure to use the service port required by the specific software package.
