If the irule only makes the http to https better use the default F5 iRule _sys_https_redirect

If not don’t forget the return in the line after the redirect and if you have that check if there are more than one iRule on the VS

Also a good idea is to close the connection so I use most times

HTTP::respond 302 noserver Location https://[HTTP::host][HTTP::uri]  Connection Close

    Thank you for your anser,

    this is the IRule who i used and i have alwayse the same problems with all hosts.

     

    when HTTP_REQUEST {

       

      if { [string tolower [HTTP::host]] contains "mysite.com"} {

         if {[HTTP::has_responded]}{return}

         #log local0. "[HTTP::host] [HTTP::uri]"

        HTTP::respond 301 Location "https://[HTTP::host][HTTP::uri]"

        regsub -all {:\d*$} [HTTP::host] "" host

         HTTP::redirect https://$host[HTTP::uri]

         return

      

      }

       

      }

      Hi mika,

      Would you try using the "HTTP::has responded" line, before if statement?

      when HTTP_REQUEST {
	if {[HTTP::has_responded]} { return }
	
	if {[string tolower [HTTP::host]] contains "mysite.com"} {
		HTTP::respond 301 Location "https://[HTTP::host][HTTP::uri]"
		return
	}
}
