Irule forwarding with various options

Hi,

instead of multiple if commands, it is recommended to use switch

when HTTP_REQUEST {
    if { [string tolower [HTTP::host]] equals "mysite.com" } {
        switch -glob [string tolower [HTTP::path]] {
            "/" - 
            "/mysite/" { HTTP::redirect https://www.bettersite.com/mysite/ }
            default {
                HTTP::redirect https://www.bettersite.com/mysite[HTTP::uri]
                return
            }
        }
    } else { HTTP::respond 301 Location https://www.mysite.com[HTTP::uri] return }    
}

when appending [HTTP::uri] to a host, do not add / as [HTTP::uri] already starts with /
