Thanks for the help, but that really was not what I was looking for. Really need to get the redirect at the node level here is the css config

 

 

Service is the node

 

 

service crystal-sw-crystalpr04-HO/DC

 

redirect-string "sw-crystalpr04/businessobjects/enterprise115/InfoView/default.htm"

 

 

Content is the virtual server

 

 

content crystal-prd-VM-HO/DC-redirect

 

vip address 10.1.4.25

 

redundant-index 15

 

add service crystal-sw-crystalpr04-HO/DC

 

add service crystal-sw-crystalpr06-HO/DC

 

advanced-balance sticky-srcip

 

flow-timeout-multiplier 75

 

primarySorryServer crystal-sw-crystalpr05-HO/DC-FO

 

protocol tcp

 

port 80

 

url "//businessobjects-infoview/*"

 

active

 

 

 

 

Are you saying that you need to redirect to another URL or that you want to select a specific node in the pool?

 

 

Just an observation: if the servers each serve a separate and distinct purpose I would consider using separate pools, if not separate VIPs. Otherwise your monitoring could easily lead to unexpected problems.

I am going to set them up on 2 VIP's, to make it easier, but for the challenging one I just need to load balance to the two servers, but I also need it to redirected to

 

 

So the VIP points to server1 and server2 and I need the redirect to be

 

 

server1/businessobjects/enterprise115/InfoView/default.htm when it is sent to server1

 

 

server2/businessobjects/enterprise115/InfoView/default.htm when it is sent to server2

 

 

 

Thanks again for the help!

When you say redirect, do you mean that you want to send an HTTP Redirect to the client to point to the actual server? ie the server is not located behind the BIG-IP, the BIG-IP is just doing smart redirecting?

Or maybe the BIG-IP redirects to the new URL on a different VS on the BIG-IP that then load balances to pool A?

From your original post it seems that what you want to do is look at the incoming URI and if it contains X then send to server A and modify the URI to be XYZ.

In pseudocode this would be:

when HTTP_REQUEST

if HTTP::URI contains "thelinkrpts"
 then   
        pool A
        URI replace with "/businessobjects/enterprise115/InfoView/default.htm"
elseif HTTP::URI contains "infoview"
 then   
        pool B
        URI replace with "/businessobjects/enterprise115/InfoView/default.htm"
else
        pool C
endif
