HTTP::redirect loop

Here is a code which will prevent redirect loops

when HTTP_REQUEST {
     Make sure only the login page matches the code, to prevent all requests to be redirected to login page (like images CSS, and other web pages)
    if {[HTTP::path] equals "/Login.aspx"} {
        set order [URI::query [HTTP::uri] order]
        set context [URI::query [HTTP::uri] context]
         Don't redirect if context already equals 3
        if { $order ne "" && $context != 3 } {
            HTTP::redirect /Login.aspx?guestlogin=1&order=${order}&context=3 
         Redirect if order is null and guestlogin doesn't equal 1
        } elseif {$order == "" && [URI::query [HTTP::uri] guestlogin] ne 1} { 
            HTTP::redirect /Login.aspx?guestlogin=1 
        }
    }
}
