asp.net - How do you push an update to a non-HTML5 browser? -

-

we considering web application provide users frequent updates system data. initially, data limited system pressure, flow, etc. concept apply many areas of our business. data stored in sql server.

the question is, how force table on webpage update when new data inserted database. example, pump reports new flow value. updates database can throttled realistically we're looking @ new update every minute or 2 our purposes.

this seems case push notification used can use asp.net? html5 out of question although we've watched push demos web sockets.

  1. is there push technology can use asp.net?
  2. if not, or if it's better solution, should poll database jquery / ajax? suggestions samples should at?

polling via ajax best solution here.

since using asp.net, of built in ajax controls can make pretty simple:

if want make better job of this, might consider creating web service , using raw javascript or jquery framework handle ajax request / update. because asp.net ajax sends full page view state server, inefficient , unnecessary.
