Oct 11, 2011iRule for redirecting to correct Pool or server
I am a little new to the iRule world but i am catching up fast. Here is a brief explanation .
I have 2 URLs or external hosts ( Mailxyz.domain.com and mobilexyz.domain.com ) both of them pointing to the Same External IP Address , let's say 200.100.100.100 . This 2 URLs are being accessed by a lot of the old Mobile devices for mail purpose on EXCHANGE 2003 Server
Note: Not exchange 2010 , it is Exchange 2003
i.e
mailxyz.domain.com -->Ext IP: 200.100.100.100 --> FW NAT --> F5 --> 10.10.10.10
mobilexyz.domain.com -->Ext IP: 200.100.100.100 --> FW NAT --> F5 --> 10.10.10.10
All clients traffic are using port 443 ( https ) to both URLs.
external traffic using URL mailxyz.domain.com are ActiveSync, OWA & RPC over Https
and
external traffic using URL mobilexyz.domain.com are ActiveSync & RPC over Https but not OWA
We recently added another server to handle new mobile devices and start migrating those old mobile devices to the new infrastructure or server.
Newmobilexyz.domain.com -->Ext IP: 200.100.100.200 --> FW NAT --> F5 --> 10.10.10.20
PROBLEM:
The traffic from the old Devices pointing to both 2 old URLs ( mailxyz.domain.com & mobilexyz.domain.com ) need to be split such that All ACTIVESYNC traffic on Port 443 ( https) is redirected by F5 to the new mobile devices server ( Newmobilexyz.domain.com ) . While the rest of the traffic still goes to the ( mailxyz.domain.com & mobilexyz.domain.com )
How can i achieve this ? i have looked into Separate VIPs, Cookie , Http Header & irules . What is the simplest way to resolve this using irules

Hi tech_cbre,when HTTP_REQUEST { switch -glob [string tolower [HTTP::header User-Agent]] { "*msie*" { do something } "*firefox*" { do something } "*chrome*" { do something } default { log local0. "Unhandled User Agent: [HTTP::header User-Agent]" } } }
