I would like to start off saying that I'm very new to programming. I am developing a site (www.example.com) that has multiple hyperlinks. 
When a user visits my site I want all the links to be defaulted to the back office of another site (www.tvcmatrix.com/mhammonds) I use. How do I set the links to redirect to the query string value based on inputted text from a form that is on my site (www.example.com)? 
In other words, if the url reads www.example.com/?user=abelliard, how do I make all the links on the site change to "www.tvcmatrix.com/abelliard"? If no query string is present, then I would like for the links to be www.tvcmatrix.com/mhammonds.
Here is a file on my site for the form called "form.asp"
<!DOCTYPE html>
<html>
    <body>
        <form action="viral.asp" method="get" name="input" target="_self">
            Your TVC Matrix Associate ID: <input type="text" name="user" />
            <input type="submit" value="Submit" />
        </form>
    </body>
</html>
Here is the "viral.asp" file in the "form.asp" file.
<%@ language="javascript"%>
<!DOCTYPE html>
<html>
    <body>
    <%
        var id = Request.QueryString("user");                    
        Response.Write("Your URL is: www.mca.com/?user=" + id)
    %>
    </body>
</html>
