when i opened that view for the second dont rerun the ajax i use this code but is not correct
Unclear. What does "not correct" mean? You have a "username" input but are not using vary by parameter. As written you are leaking user information which is a very poor design. Is this what's not working as expected? You keep getting the same user information
when the username changes?
caching does not stop the ajax call, it just caches the result. but in your case, as the response varies by user, the server can not cache, and by default the browser does not cache ajax calls.
the correct solution is for the client code to cache the result in a cookie or local storage and only make the ajax call when necessary.
To reiterate, you need to vary by the username parameter otherwise every application user your will see the same cached result set by the first user. Then by the first user to hit the action every 1000 seconds.
There can be other issues with the design. Every time the autocomplete is invoked, it appends the same cached data to the HTML table. The design seems a little off but perhaps we do not have the entire design picture.
Anyway, the official Output Cache documentation is quite good. The docs explain the definitions with sample code.
Please stop asking the same question over and over. If the solutions in your previuos threads are not working as expected then explain what's not working. Asking he same question wastes the community's time. Please stop!

Your requirement is not clear. I think you expect the done() promise should not fire if the Output Cache is enabled. That's not how AJAX works.
What's a little confusing is you're executing an AJAX request when the page loads. Why? Simply populate the page from the server rather than making two HTTP requests.

Your code does NOT return a View! It returns JSON.
Anyway, I built a basic text using the official and openly published OutPutCache documentation and caching simply just works as written in the docs.
https://forums.asp.net/t/2164595.aspx?how+to+cash+view+
// GET: AdventureWorks [OutputCache(Duration = 60, VaryByParam = "lastName")] public JsonResult check_user_permission_Module(string lastName) { List<string> people = db.People.Where(p => p.LastName == lastName).Select(m => m.FirstName).ToList(); return Json(people, JsonRequestBehavior.AllowGet); }Unclear. What does "not correct" mean? You have a "username" input but are not using vary by parameter. As written you are leaking user information which is a very poor design. Is this what's not working as expected? You keep getting the same user information when the username changes?

The SO thread you shared explains why layout.cshtml cannot be cached. This fact is mirrored in the links I've provided in you previous threads. Why do you NOT believe the reference documentation? Also, in your previous threads, you are not returning JSON not a View yet you keep asking about Views.
At this point it seems you need to take a step back and learn the fundamentals. Asking the same question over and over is not going to change the results. Lastly, share your code so we can review your code.
