irule based redirection issue

Like that

when HTTP_REQUEST {

     STREAM::disable
     if { [string tolower [HTTP::path]] equals "/" } {
            if { ![HTTP::path] starts_with "/fr" && ([HTTP::header "Accept-Language"] starts_with "fr") } {
                HTTP::redirect "https://www.mylocalnet.us/fr/pages/default.aspx"
            }
            else { 
                HTTP::redirect "https://www.mylocalnet.us/en/pages/default.aspx" 
            }
        }

        switch -glob [string tolower [HTTP::path]] {
            "/en/sitemap.xml*" {
                HTTP::uri "/en-sitemap.xml"
            }
            "/fr/sitemap.xml*" {
                HTTP::uri "/fr-sitemap.xml"
            }  
        }
      }

    when HTTP_RESPONSE {
         catch and replace redirect headers
        if { [HTTP::header exists Location] } {
            HTTP::header replace Location [string map {"http://" "https://"} [string tolower [HTTP::header Location]]]
        } 
          only look at text data
        if { [HTTP::header Content-Type] contains "text" } 
             create a STREAM expression to replace any http:// with https:// for CDN
            STREAM::expression {@http://bt.mylocal.ae@https://bt.mylocal.ae@ @www.mylocalnet.us@ 
    @http://www.mylocalnet.us@https://www.mylocalnet.us@}
             enable STREAM
            STREAM::enable
        }
    }
