今天更新了框架中的Redis驱动ServiceStack.Redis，最新版本4.0.5.0。
在做简单压力测试时出现异常，提示每小时允许6000个请求。
The free-quota limit on '6000 Redis requests per hour' has been reached. Please see https://servicestack.net to upgrade to a commercial license.

Free Quotas
Whilst ServiceStack v4 is a commercially-supported product, we also allow free usage for small projects and evaluation purposes.
The NuGet packages above include the quota's below which can be unlocked with a license key:
- 10 Operations in ServiceStack (i.e. Request DTOs)
- 10 Tables in OrmLite
- 20 Different Types in JSON, JSV and CSV Serializers *
- 20 Different Types in Redis Client Typed APIs
- 6000 requests per hour with the Redis Client
* These quotas are lifted in ServiceStack.Client generic service clients allowing un-restricted access when consuming ServiceStack services.
ServiceStack 4.0 开始已经成为商业产品，不在完全免费，不过突然来这么一下真是措手不及。
推荐大家一个Redis Http API 组件，https://code.google.com/p/redbridge/ 。
希望大家在使用任何开源组件新版本的时候，切记测试，小心掉坑里！
