Does a website on IIS10 go into a "sleep mode" after a certain amount of time?

I'm using a job scheduling app using Hangfire and it relies upon a website built in ASP.NET. The problem is that when I leave the website idle for 12 hours or so the Hangfire jobs no longer (it is a text messaging system) process. Finally, when I launch the website by accessing it through https://www.CrudibleTARS.com, the website appears to "wake up" and the jobs process properly.

My question is this: Even thought IIS 10 is showing that the website is "started" the jobs do not process. So, does a website "go to sleep" after a period of inactivity? Is there a way to stop this if so?

I would have asked this on the the Hangfire site but they do not answer questions in a timely manner, if at all. In any event, this is not a Hangfire problem this is IIS 10 ... website status problem/question.

Thanks,
C. T. Blankenship

What I have tried:

Restarting the website ... injecting four records into the messaging database table ... and noticing that the jobs do not execute.

Then, I launched the website using Google (not IIS on the server) and the jobs execute.

Since we have no idea how your application uses the website it is impossible to suggest anything.

Impossible ... not so much ... but thanks for commenting.

I think this solution should work just fine ... Changing IIS to Not Stop Worker Process in IIS 7.0+ I'll keep this thread updated with regards to this possible solution.

This link is the solution to the problem I believe Changing IIS to Not Stop Worker Process in IIS 7.0+ in the previous comment the link was incorrect.

I installed SmarterPing (http://www.smartertools.com/Products/SmarterPing/Default.aspx) and set it up to ping my website every 10 minutes. The installation was not without events though. I had to set it up to emulate Windows 7 and to run the .exe as Administrator. Thanks so much to all of you for offering your insights. There is one problem with using the application though. It is no longer supported by SmarterTools. If you have a problem you are on your own. I'm glad I figured it out as my first attempt to install the application failed.

Thanks!

This does happen in IIS, and the simplest way of solving this can be to ping your application at constant interval of time if you want to keep the application active.

Another way of handling this problem is by changing the idle time in the application pools, see this thread for more on that, Preventing IIS from "falling into sleep"[^]. This is the efficient way of handling the problem, since you can handle it from the control panel without having to add an extra service in the game.
