This will allow me to switch from my HAProxy homegrown solution to AppMesh

You can use cookie values in routing using the header based routing which is launched in our Preview Channel. Check it out and let us know what you think! https://github.com/aws/aws-app-mesh-examples/tree/master/blogs/http-headers-and-priority

I think we can moved this to done for now. Today you can match cookies by matching the Cookie header using regex.

For example, if you wanted to match http requests that had a cookie named my_cookie, you could write:

{
  "httpRoute": {
    "match": {
      "headers": {
        "name": "cookie",
        "match": {
          "regex": "my_cookie=[^;]*"
        }
      }
    }
  }
}

We can certainly revisit this to improve the ergonomics of it a bit. Please feel free to chime in on this issue if you'd like to see us iterate on this.
