How to handle an application launch event in an ASP.NET module

Question

I am writing an asp.net HTTP module that must read configuration data once from a local file (for example, config.xml stored in the root directory of the application), and then, based on the configuration, do some processing of incoming requests.

Since there are no Application_Start / Application_init connections in Asp.NET modules, what would be the best way to handle this scenario. I try to avoid reading the configuration file every time a request arrives. Ideally, I want to read the configuration file when the application starts.

I need to encode this only in the http module and not use Global.asax

static string test; 
        public void Init(HttpApplication application)
        {


            application.BeginRequest +=(new EventHandler(this.Application_BeginRequest));
            test = "hi"; 
            application.EndRequest +=(new EventHandler(this.Application_EndRequest));


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


        }
