[keycloak-dev] browser backbutton

[Libor Krzyzanek]

Just read the discussion so let me clarify few things.

Redirects
I’m fine with one redirect after POST. But it needs to be one redirect not 3. I was complaining about 3 additional redirects after hitting “LOGIN” button.
In apps that I’m author (e.g. planet.jboss.org) I exactly use that pattern - after HTTP POST server returns 302 redirect to another page which helps with a) refresh button problem, b) browser back button problem.

Back button:
From UX perspective the back button must work. Everybody use it. On Mac/iPad users are used to use gesture. I use it everywhere.
Personally when I come to some site which is trying to force me to use back button on page instead of back button in browser I always feels like using website written 5 years ago.

Other comments inline.

Thanks,

It doesn’t disable the back button. The browser just don’t use internal browser cache when the URL is visited either by refresh button or back button.

From UX perspective back button on webpage needs to behave exactly same as back button in browser.

Cancel is very confusing for me. For example on “Forgot password” is cancel button - what is purpose of it? what happen when I click on it? Where I would be redirected? I personally removed those cancel buttons from our theme because it’s not clear why they’re there.
