Answer Area

void ClearCachedTeams()

{

lv
Database cache = Connection.GetDatabase();
Cache cache = Connection.GetDatabase();

lv

cache.KeyDelete(‘Team’);

/cache.StringSet(‘Team’,”);
cache.ValueDelete(‘Team’);
cache. StringGet(‘Team’,”);

ViewBag.msg += “Team data removed from cache.”

}

Box 1: IDatabase cache = connection.GetDatabase(); Connection refers to a previously configured ConnectionMultiplexer.

Box 2: cache.StringSet("teams",") To specify the expiration of an item in the cache, use the TimeSpan parameter of StringSet.

cache.StringSet("key1", "value1", TimeSpan.FromMinutes(90)); Reference: https://azure.microsoft.com/sv-se/blog/lap-around-azure-redis-cache-preview/ https://docs.microsoft.com/en-us/cli/azure/webapp/config/container.
