cache-aware-clients need enhance

[1257960069]

https://docs.servicestack.net/cache-aware-clients
the sample code from docs:

var sharedCache = new ConcurrentDictionary<string, HttpCacheEntry>();

IServiceClient msgPackClient = new MsgPackServiceClient(baseUrl).WithCache(sharedCache);

IServiceClient jsonClient = new JsonHttpClient(baseUrl).WithCache(sharedCache);

issue:
how to control the sharedCache lifetime?
just work at a method body?

https://docs.servicestack.net/csharp-client#cache-aware-service-clients
the sample code from docs:

IServiceClient client = new JsonServiceClient(baseUrl).WithCache(); 
//equivalent to:
IServiceClient client = new CachedServiceClient(new JsonServiceClient(baseUrl));

issue:
WithCache can not work, because of not exist long litetime's ConcurrentDictionary<string, HttpCacheEntry>()
by new CachedServiceClient(ServiceClientBase client)

It's not meant to be static, you can register it as a singleton to reuse the cache.

of cource, i can do it. the root issue is that your sample code:
IServiceClient client = new CachedServiceClient(new JsonServiceClient(baseUrl));

we can not new CachedServiceClient every time
