Configuration (stand-alone/classical apps)

Add the configuration settings into your app.config/web.config file

Configure with two seperated sections

<?xml version="1.0" encoding="utf-8"?>
<configuration>
	<configSections>
		<section name="memcached" type="Enyim.Caching.Configuration.MemcachedClientConfigurationSectionHandler,Enyim.Caching" />
		<section name="redis" type="net.vieapps.Components.Caching.RedisClientConfigurationSectionHandler,VIEApps.Components.Caching" />
	</configSections>
	<memcached>
		<servers>
			<add address="192.168.1.2" port="11211" />
			<add address="192.168.1.3" port="11211" />
		</servers>
		<socketPool minPoolSize="10" maxPoolSize="512" deadTimeout="00:01:00" connectionTimeout="00:00:05" receiveTimeout="00:00:05" />
	</memcached>
	<redis>
		<servers>
			<add address="192.168.1.4" port="6379" />
			<add address="192.168.1.5" port="6379" />
		</servers>
		<options abortConnect="false" allowAdmin="false" connectTimeout="5000" syncTimeout="2000" />
	</redis>
</configuration>

Configure with only one section

<?xml version="1.0" encoding="utf-8"?>
<configuration>
	<configSections>
		<section name="cache" type="net.vieapps.Components.Caching.CacheConfigurationSectionHandler,VIEApps.Components.Caching" />
	</configSections>
	<cache provider="Redis" expirationTime="30">
		<servers>
			<add address="192.168.1.2" port="11211" type="Memcached" />
			<add address="192.168.1.3" port="11211" type="Memcached" />
			<add address="192.168.1.4" port="6379" type="Redis" />
			<add address="192.168.1.5" port="6379" type="Redis" />
		</servers>
		<socketPool minPoolSize="10" maxPoolSize="512" deadTimeout="00:01:00" connectionTimeout="00:00:05" receiveTimeout="00:00:05" />
		<options abortConnect="false" allowAdmin="false" connectTimeout="5000" syncTimeout="2000" />
	</cache>
</configuration>

Example of usage (stand-alone/classical apps)

public class CreativeService
{	
	using net.vieapps.Components.Caching;

	Cache _cache;
	Cache _memcached;
	Cache _redis;

	public CreativeService()
	{
		this._cache = new Cache("Region-Name"); // with default caching provider is 'Redis'
		this._memcached = new Cache("Region-Name", "memcached");
		this._redis = new Cache("Region-Name", "redis");
	}

	public async Task<IList<CreativeDTO>> GetCreativesAsync(string unitName)
	{
		return await this._cache.GetAsync<IList<CreativeDTO>>($"creatives_{unitName}");
	}

	public async Task<IList<CreativeDTO>> GetMemcachedCreativesAsync(string unitName)
	{
		return await this._memcached.GetAsync<IList<CreativeDTO>>($"creatives_{unitName}");
	}

	public async Task<IList<CreativeDTO>> GetRedisCreativesAsync(string unitName)
	{
		return await this._redis.GetAsync<IList<CreativeDTO>>($"creatives_{unitName}");
	}
}
