I am having a simple JSP (Page1.jsp) at one server, which calls another JSP (Page2.jsp) at another server.
The Page2.jsp application uses acegi as Spring security and has NTLM authentication along with normal login functionality.

My problem is when I am submitting Page2.jsp from Page1.jsp, inspite of escaping the url in acegi filter, I am getting popup window for user authentication.

Here is the code i used in my acegi.xml to escape the authentication:

<bean id="filterChainProxy"
<property name="filterInvocationDefinitionSource">

Is there any way where I can set the user credentials in NTLM API so that popup window can be avoided?
