Irules Data-Group

Syntax should be correct - I saved it on my F5 OK, however to create your datagroup before you try to save the iRule - I am assuming you are using v10?

b shell
class dg_parveez_dynamic_pools {
{
    "apctdev.leni2.com-VS-HTTP" { "pool_apctdev.leni2.com_http" }
    "apbuild.leni2.com-VS-HTTP" { "pool_apbuild.leni2.com_http" }
    "apctdev.leni2.com-VS-HTTP" { "pool_apctdev.leni2.com_http" }
    }
}
save

Then here is the iRule - you will need to update the line "pool $static_pool" yourself;

when CLIENT_ACCEPTED { 
    set default_pool [LB::server pool] 
    log local0. "Default pool [LB::server pool] set" 
    log local0. "Client IP is [IP::remote_addr]" 
}

when HTTP_REQUEST { 

    switch -glob [HTTP::uri] {
             "/" {
            log local0. "redirecting from /"
            HTTP::redirect "http://www.parveez.com" 
            return
           pool pool_parveez.com-http 
        }

        "/iss_static*" {
            pool $static_pool
            return
        }

        default {
            pool [class match -element [string tolower [virtual]] starts_with dg_parveez_dynamic_pools ]
            return
        }
    }
}

Good luck and have a nice weekend - I am off now!!
