301 iRule redirection generating an extra 301 status code?!?

Hi,

May I suggest to use the irule below instead :

when HTTP_REQUEST { 
    if { [string tolower [HTTP::host]] eq "sitename.com" } { 
        HTTP::respond 301 Location "https://www.sitename.com[HTTP::uri]" Test TestRedirect Connection Close
    }
}

I think that the irule originally posted may generate a loop on the client side. moreover, you should see TCL errors on ltm log files as then keyword is not supported (AFAIK)

Do you have a backend that is listening on http ? Can you check that this is really the F5 that generate the redirect not the backend ?

In my example, a redirect caused by F5 should generate a specific header named Test to be sent with the redirect response.
