uri limit count

 v10.x data group mapping old URIs to new URIs
 Define this in the GUI under iRules | Data Group List or 
 by merging this config into your existing config:
 
class uri_mapping_dg {
   {
      "/old_uri1" { "/new_uri1" }
      "/old_uri2" { "/new_uri2" }
   }
}

 v11.x data group:
ltm data-group internal uri_mapping_dg {
    records {
        /old_uri1 {
            data /new_uri1
        }
        /old_uri2 {
            data /new_uri2
        }
    }
}

 iRule which looks up the client requested URI to get a match
when HTTP_REQUEST {

log local0. "[IP::client_addr]:[TCP::client_port]: [HTTP::method] to [HTTP::host][HTTP::uri]"

 Check if URI starts with a URI from the mapping data group
set redirect [class match -value [HTTP::path] starts_with uri_mapping_dg]

if {$redirect eq ""}{
 Take some default action for URIs which do not match the data group?
log local0. "[IP::client_addr]:[TCP::client_port]: No match for [HTTP::uri]"
} else {
HTTP::redirect $redirect
log local0. "[IP::client_addr]:[TCP::client_port]: Redirecting to $redirect"
}
}
