Hi,
i am trying to make my API service to query my SQL DB every 5 minute, hold his response and share this response with the all next 5 minutes calls.

So, is there a way that i can run the query with timer? and how can i hold the response.
I tried to work with session but i don't know if it is the right way and how exactly to that.

Timer is not a possibility inside web application...
What you may do is to store your response on the Application level accompanied with a time stamp...If time stamp is older than the period you want you should reload your response and store it instead of the current, otherwise return the existing one...

C#

if((DateTime.UtcNow - Application["LastQuery"]).TotalSeconds > 300)
{
  Application["Response"] = LoadData();
  Application["LastQuery"] = DateTime.UtcNow;
}

// use Application["Response"] as your answer

sorry, but is it "Application" that you used?

Kornfeld Eliyahu Peter 7-Dec-15 8:06am

Application. Yes. That's something you can share across all of your sessions...

For a record: a timer is possible, say, on the client side only. In majority of cases, the use of timers is a bad thing; it can be and should be avoided.
