how can i troubleshoot an irules logic

kevin

i think i've resolved this but i'd be keen to hear your views

i ran the logging you suggested with both client_addr and remote_addr but it showed my ip address in both fields so i thought maybe the ltm isn't seeing the address (10.27.1.254) i was using in my address data group

log local0. "node ip [server_addr] client ip [IP::client_addr] LB ip [LB::server] HTTP HOST [HTTP::host ] HTTPURI [HTTP::uri]"

i'm using the virtual ip on the ltm as an explicit proxy so whenn the client requests a url the source ip is the client but the destination ip is the ltm not the ip address in the url

so i think the only way to pick up the address 10.27.1.254 in the url is by using a string data group with the http::host variable and then manipulate where to send it then

does this make sense?

thanks again for your help, its greatly appreciated
