What is this?

I'm trying to replicate an issue I'm having with Tower Sessions, where the session seems to be missing data upon initial return from Stripe, but if you manually enter the URL, it works.

How to run

In order to demonstrate the issue, the "stripe" service must be run on a different origin than the "princess" service. The following will set that up:

cargo run --bin=stripe & cargo run --bin=princess -- http://$(hostname):4001/

Now visit http://localhost:4000/ and click the buttons. At the end, you'll end up at a page at http://localhost:4000/success and see the test data inserted in the initial get of /, or a message indicating failure. To see it succeed, run:

cargo run --bin=stripe & cargo run --bin=princess

and follow the buttons starting from http://localhost:4000/ again to the end.

Why is it called "princess"?

Because it's the baby version of Queenie, a small service using the same crates that sends users to Stripe and then receives a redirect from there once a user has successfully paid. I just wanted to get a minimum test case.
