Irule to access individual web servers

Thanks - I am testing this on one of our QA BigIps before using it in production, I found a similar devcentral request and eventually put the following in the Node Select Expression Box: node(findstr(http_uri, "ip=", 3, '/') + ":80") This added without the error message. However, when I try to test it out it doesn't seem to be working. To test this I should be using: www.website.com/ip=10.10.10.1 (10.10.10.1 being the Node IP address of one of the pool members.) I set up a static page to verify what server I am hitting but when I put the full url/ip= info in I keep getting a Page Cannot be Found. Where am I going wrong?
