Custom URLRewriting with XML and Global.asax

utilizes my custom DocParser class here

 void Application_BeginRequest(object sender, EventArgs e)
        //string path = Request.Url.ToString();
        string path = Request.Path;

        if (Regex.IsMatch(path.ToLower(), ".*[.](jpg|png|gif|css|js|pdf|ico|woff|svg|eot|ttf)$"))
            //var h = Regex.Replace(path.ToLower(), ".*/(.*)/(.*)$", "~/$1/$2", RegexOptions.Singleline);
        //TODO: authorize user/request
 DocParser dp = new DocParser(Server.MapPath("~/rewrite.xml"));
        var rules = dp.GetElements("*/rule");
        foreach (var r in rules)
            if (string.IsNullOrEmpty(r.match_url)) {
                Shared.HandleError("Global.asax::null or empty match_url encountered");

            if (string.IsNullOrEmpty(r.action_url))
                Shared.HandleError("Global.asax::null or empty action_url encountered");
            if (Regex.IsMatch(path, r.match_url,RegexOptions.IgnoreCase))
                List<object> qsvars = new List<object>();

                foreach (Match m in Regex.Matches(path, r.match_url, RegexOptions.IgnoreCase))
                    for (int i=1;i<m.Groups.Count;i++)
                //Context.RewritePath(string.Format(r.action_url,qsvars.ToArray()) + "&rewrite=1");
                Context.RewritePath(string.Format(r.action_url, qsvars.ToArray()));
