iRule Question - https to https://www

Hello,

The irule that use a switch will cause a loop when doing requests with www.def.com hostname

I suggest this :

when HTTP_REQUEST {
    switch -glob [string tolower [HTTP::host]] {
        "def.com" {
            HTTP::redirect https://www.def.com[HTTP::uri]
        }
        "www.def.com" {
              do nothing
        } 
        default {
            reject
        }     
    }
}
