Modificatioin of irule to append www

Please explain what you want to do...

in description, you talk about https:// and in irule, you redirect to http service

So :

• if the client requests http://abc.com --> you can redirect to http://www.abc.com without error
• if the client requests http://abc.com --> you can redirect to https://www.abc.com without error
• if the client requests https://abc.com --> you can redirect to https://www.abc.com but you can't prevent TLS error if you don't have a certificate for abc.com. TLS certificate if sent by the server before you can redirect...

You can try this code:

when HTTP_REQUEST {
    set host [HTTP::host]

     evaluate host starting with "www." if we need to insert it in redirect.
    set redirectHost [expr {$host starts_with "www" ? [getfield $host ":" 1] : "www.[getfield $host ":" 1]"} ]

     evaluate if service is http or https / host starts with "www." If one of these condition is false, prepend to the redirect URI https://$redirectHost
    set redirectURI [expr {![PROFILE::exists clientssl] || !($host starts_with "www.") ? "https://$redirectHost" : ""}]

     If path equals / change URI to "/XYZ.Web/Login.aspx"
    append redirectURI [expr {[HTTP::path] equals "/" ? "/XYZ.Web/Login.aspx" : [HTTP::uri]}]

     if the URI requires to redirect,redirect to $redirectURI, else, forward to pool as configured in virtual server.
    if {!($redirectURI equals [HTTP::uri])} {
        HTTP::redirect $redirectURI
    }
}
