Question : Using ASPX redirect and SEO impact

Greetings - I use a simple ASPX redirect, on my shared hosting account. Pat of code is listed below for reference. I assumed search bots, etc understood redirects, but I have noticed some inconsistency when I run SEO tools and other web site testing software. My questions are (1) Are redirects an acceptable and optimal way to redirect host names to sub directories, since my host will not allow host names to point to subs (2) Will a redirect impact SEO rankings (3) As the attached image shows, some SEO or web site checking tools believe the links are bad since they are searching for links then appending the found links to the end of the host name (4) For links, should the "master" link i.e. "www.hostname.com/sub/sub" be explicitly listed in every page?


//Part of code
    If InStr(UCase(Request.ServerVariables("SERVER_NAME")), UCase("website.com")) > 0 Then
        Response.Redirect("/www/website/")
