Browser back redirects to "/saml/SSO" page.

[Charmal Damith P]

Hi all,

When I run the test project, click the provider and logged to the provider's system.

Provider redirect to the landing page (/landing) with the correct user name.

If I press browser back button twice sometimes page redirects to the "/saml/SSO" with following error appears.

Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.
