Access specific node with irule

Hi Everyone,

Client needs to access a specific pool member. there are 4 pool members sitting behind a VS. i Have implemented a irule,

when HTTP_REQUEST { set member_param "server" set base_pool [LB::server pool] set member_role "" set uri [HTTP::uri] set data_group [HTTP::host] }

so that the client can add the server name/ip to the url and access the specific pool member. But it does not work.

i am not sure if i am doing something incorrect in this.

please give your valuable answers and suggestions.
