How to stop "Confirm Form Resubmission" popup in Chrome after submitting POST request during SAML Authentication
We are using SAML 2.0 protocol to login to our application. Login binding is HTTP POST. When the user submits the url in chrome browser, they would be shown a popup to enter the credentials. After clicking ok, Immediately we see an additional popup "Confirm Form Resubmission". This is happening only in chrome. We traced the network traffic and see that a GET request is being fired immediately after HTTP POST in chrome against the IDP End point. This GET request is not happening in chrome.
This is not happening if we use HTTP Redirect method as login protocol binding but we do not want to use HTTP Redirect as it exposes the request in url.
