Update url when query/mutation change?

[thanhpd56]

Hi,
I see that the graphiql support generate url base on our query or mutation.
For example: https://graphql.org/swapi-graphql?query=%7B%0A%09film(id%3A%201)%7B%0A%20%20%20%20title%0A%20%20%7D%0A%7D
Whenever I change the query, the url will be changed.

This feature will help us to share the query easily.

However when I run the your example, the url does not change like above example.
How can I enable it?
Thanks.
