How to cache to file?

[vuminhquang]

Hello,
If I want to use CacheManager to cache to file, with no expiration, instead of memory, do anyone know where to start to code this?

Thank you

At first, you should ensure that CacheManager can write cache data to file, if not, you should do this by yourself.

What's more, overwrite Ocelot.Cache.CacheManager this project, to change the ExpirationMode

Ocelot/src/Ocelot.Cache.CacheManager/OcelotCacheManagerCache.cs

Lines 15 to 18 in 41519b1

	public void Add(string key, T value, TimeSpan ttl, string region)
	{
	_cacheManager.Add(new CacheItem<T>(key, region, value, ExpirationMode.Absolute, ttl));
	}

@catcherwong : thank you for answering me. Seems that CacheManager don't have feature which writes cache data to file, I will try to write a new CacheManager service for Ocelot.
Since I am not familiar with IoC, I am very appreciate if you could show me (when you have spare time) how to inject the new service in Startup.cs. Thank you.
