if I'm using kratos & hydra, and I have kratos redirecting to URL

/test

after login, what have people been using to persist the

challenge

value so that on

/test

I can accept the login request on hydra after? cookie? something else?

When you initiate the self-service login flow for browsers using Kratos, you can use the

return_to

url query parameter and specify the

login_challenge

over there.
