Set a ServerVariable in a IIS 7.0 httpmodule

I'm trying to set a servervariable ("LOGON_USER") in a httpmodulle in IIS 7.0, but I'm not archieving it.

My BeginRequest function, so far...

        BindingFlags temp = BindingFlags.NonPublic | BindingFlags.Instance | BindingFlags.Static;


        MethodInfo addStatic = null;
        MethodInfo makeReadOnly = null;
        MethodInfo makeReadWrite = null;


        Type type = application.Request.ServerVariables.GetType();
        MethodInfo[] methods = type.GetMethods(temp);
        foreach (MethodInfo method in methods)
        {
            switch (method.Name)
            {
                case "MakeReadWrite": makeReadWrite = method;
                    break;
                case "MakeReadOnly": makeReadOnly = method;
                    break;
                case "AddStatic": addStatic = method;
                    break;
            }
        }

        makeReadWrite.Invoke(application.Request.ServerVariables, null);
        string[] values = { "LOGON_USER", "test" };
        addStatic.Invoke(application.Request.ServerVariables, values);
        makeReadOnly.Invoke(application.Request.ServerVariables, null);

During my searches I've read that this solution would work on older IIS's, but not on IIS 7.0 or 7.5.

Any idea on how can it be done in IIS 7.0?

Thanks

Solved:

    HttpApplication application = (HttpApplication)source;
    HttpContext context = application.Context;

    context.User = new GenericPrincipal(new GenericIdentity("test"), null);

new GenericPrincipal(new GenericIdentity("test"), null) will place "test" in the LOGON_USER variable

When setting server variables using the URL rewrite module of IIS you have to explicitly specify which server variables you allow to be set. This might be necessary for your own code as well. See: http://learn.iis.net/page.aspx/686/setting-http-request-headers-and-iis-server-variables/ (and search for 'Allowing server variables to be changed')
