I am writing a httpmodule for umb 7.2

But i only want it to take action on the frontende of the website, not when in the backend.

Any ideas?

 private void Application_BeginRequest(Object source, EventArgs e)
    {
        HttpApplication application = (HttpApplication)source;
        HttpContext context = application.Context;

       
        string UrlReferrer = context.Request.UrlReferrer.GetLeftPart(UriPartial.Authority).Replace("https://", "").Replace("http://", "");
        bool doRedirect = false;


        if (System.Configuration.ConfigurationManager.AppSettings["domain.redirectToCaseFromUrls"] != null)
        {
            if (System.Configuration.ConfigurationManager.AppSettings["domain.redirectToCaseFromUrls"].ToString() != "")
            {
                string[] refs = System.Configuration.ConfigurationManager.AppSettings["domain.redirectToCaseFromUrls"].ToString().Split(new char[] { ',' }, StringSplitOptions.RemoveEmptyEntries);

                foreach (string item in refs)
                {
                    if (item.IndexOf(UrlReferrer) >= 0)
                    {
                        doRedirect = true;
                    }
                }
            }
        }
}
