Content rules / redirect dynamic url CSS11501


I have a css11501 and I have a situation where there are 2 servers in disparate datacenters, that I would like to balance requests to, based on URL requested - using http redirects.

Clients come in and request http://X.X.X.X:4100/blah/whatever.aspx?foo=bar

I want to redirect requests to X.X.X.X on port 4100 that contain /blah/whatever.aspx and http redirect them to Y.Y.Y.Y:4100 and Z.Z.Z.Z:4100 preserve the rest of the request (/blah/whatever.aspx?foo=bar). Can I do this? The args passed to whatever.aspx are dynamic -- I just want to http redirect to a couple of different servers, and preserve the entirety of the request, changing only the destination IP.

How could I do this?

Re: Content rules / redirect dynamic url CSS11501

do you really need an http redirect ???

The way it normally works is that the CSS will listen on x.x.x.x port 4100 and loadbalance between the 2 servers y.y.y.y and z.z.z.z.

When forwarding the traffic to the servers, the CSS will replace the initial destination ip x.x.x.x with one of the server's ip without changing the content of the data.

This is the default behavior.

There is nothing special to do.

You have to make sure that the server response comes back to the CSS. You can do this by adjusting your routing table on every device between css and servers, or you can have the CSS nat the client ip address with one of its own.

Here is a sample config

service srv1

ip address y.y.y.y


service srv2

ip address z.z.z.z


owner MyCompany

content Application1

vip address x.x.x.x

proto tcp

port 4100

add service srv1

add service srv2


That's all for the first part.

If you need client nat you add the following

group ClientNat

vip address x.x.x.x

add destination service srv1

add destination service srv2


Done. !
