I am using a iframe portlet in a page to embed an external web app with authentication using post data. Everything is working fine until I reload the page using the browser. Then the page loading is hanging on an infinite request loop.
Steps to reproduce:
- Add a iframe portlet to any page of your portal.
- Configure it to use the "form" authentication type, either GET or POST method
- Save your configuration: now the portlet is showing you the site you have set in configuration.
- Reload the page (hit browser reload button): page loading will hang.
Note that the infinite request loop happens only with "form" authentication, not with "basic" or without authentication at all.
