Http authentication ajax jquery
Http authentication through ajax jQuery.
- Force HTTPS for authentication.
- Allow testing HTTPS without installing a certificate locally.
- Implement a RESTful LoginService that allows users to login.
- Implement login with Ajax, with the request coming from an insecure page.
