Where is best place to store ObjectContext instance?

Question

I using extension for Object, because it provides very short accessible string.

public static BusinessLayer.Models.SearchEngineEntities db(this object o)
 {

  if (HttpContext.Current == null)
   return new BusinessLayer.Models.SearchEngineEntities(ConfigurationManager.ConnectionStrings["SearchEngineEntities"].ConnectionString);

  if (HttpContext.Current.Items.Contains("DataContext"))
  {
   return (BusinessLayer.Models.SearchEngineEntities)HttpContext.Current.Items["DataContext"];
  }

  BusinessLayer.Models.SearchEngineEntities context = new BusinessLayer.Models.SearchEngineEntities(ConfigurationManager.ConnectionStrings["SearchEngineEntities"].ConnectionString);
  HttpContext.Current.Items.Add("DataContext", context);
  return context;
 }

So in a result I have execution string like:

"".db().Users.Include("")....

But I'm not 100% sure that is best solution. I hope you know better than me, where and how to store DataContext or ObjectContext instance. Maybe you know better solution...

Thank you in advice.

Why do you need an Extension Method to do this? You should abandon the extension method and use just a static method (and a static class). Also I found an article that I think it might help you:
