Add Cache System to Web Project

[ikesnowy]

Using midiatR, we could easily archive something like this to simplify query cache.

public class CacheBehavior<TQuery, TResponse> : IPipelineBehavior<TQuery, TResponse>
    where TQuery : ICachableQuery
    where TResponse : ICachableQueryResponse
{
    public async Task<TResponse> Handle(TQuery request, CancellationToken cancellationToken, RequestHandlerDelegate<TResponse> next)
    {
        if (request.AllowCache == false)
        {
            return await next();
        }

        var cacheResult = await _cacheService.Get<TResponse>(request.CacheKey);
        if (cacheResult is not null)
        {
            return cacheResult;
        }
        var freshResult = await next();
        await _cacheService.Add<TResponse>(request.CacheKey, request.CacheTime);
        return freshResult;
    }
}
