How to Implement IMemoryCache in a Server That Hosts Multiple Applications?

[sohlae]

According to the documentation, implementing IMemoryCache is something like this.

_memoryCache.GetOrCreate("cache_key",
    cacheEntry =>
    {
        cacheEntry.SlidingExpiration = TimeSpan.FromSeconds(3);
        return DateTime.Now;
    });

My question is, if I am deploying my application in a server that hosts several other applications, and say another application decided to store something in the cache using the key "cache_key", will it overwrite my cache data? If yes, is it a good practice then to give a more specific name for the cache key?

Not if it's another app.
