How to get numbers of online users using .NET Identity 2.0 in MVC 5
Do guys know that how to get numbers of online users using .NET identity 2.0 membership providers in MVC 5 ?
I have scan the methods in UserManager that Identity sample gives but no helping.
This should be somewhat accurate at displaying the user count. It uses a cache to store the user's IP address and returns a count of individual IPs. If two people are behind the same proxy it will count it as one person.
using System.Runtime.Caching;
public int UsersOnlineCount
{
get
{
return MemoryCache.Default.Where(kv => kv.Value.ToString() == "User").Count();
}
}
The best way of making sure everyone gets added to the cache is to define some BaseController with this in the constructor...
public BaseController() : base()
{
CacheItemPolicy policy = new CacheItemPolicy();
policy.AbsoluteExpiration = DateTime.UtcNow.AddMinutes(20);
MemoryCache.Default.Add(System.Web.HttpContext.Current.Request.UserHostAddress, "User", policy);
}
