Hi,
We have existing web application but need to secure with Spring.
I have used custom authentication-manager and and custom filter. The Authentication Provider calls Database for authentication. After successful authentication able to forward to the default URL but the form fields are nullified as new request is created.
The existing application has some logic on those hidden fields and we don't want to touch existing code base.
How to go about it. In short how to not to erase the existing HTTPRequest?
