**1. greedying** 提问：

>我发现 MOSN 去 cookie 时候，如果取不到，则返回中横线。这里万一 cookie 值就是中横线怎么办呢？

A：你用啥接口取得？

>用变量取的,前缀加 cookie 的 key。

>>MOSN 代码就是这么写的，那个 ValueNotFound 是一个短横，这是一个 feature 还是 bug？

A：哦 确实，这儿应该返回 error 就行了，不然任何值都有可能不对。

要这样处理才合理，通过 error 来判断了。

**2. 卿同学** 提问：

>我看 Layotto 也在推动和 Envoy 的融合，这一块现在有进展吗？

A：今年我们首先会开源 Envoy 的 cgo 插件，然后基于这个插件，可以把 Layotto 跑在 Envoy 上。
