title: How2: what event to hook in HttpModule for putting js links into head element
body: <p>I want to have HttpModule to inject javascripts, css links into HEAD element from some simple config data. I am not sure which event I should hook?</p>
  
  <p>Curently I use<br>
  - context.PreRequestHandlerExecute for changing the masterpage dynamically<br>
  - Context.BeginRequest for SEO optimalization  </p>
