Spring Security: multiple security context but returns wrong authentication-failure-url

I am using Spring Security version 3.1.2. Here is the configuration: ``` <http pattern="/embedded/**" auto-config="true" use-expressions="true" access-denied-page="/embedded/login.htm"> <intercept-url pattern="/embedded/login-embedded.html" access="hasRole('ROLE_AUTHENTICATED')"/> <intercept-url pattern="/embedded/**" access="permitAll"/> <form-login login-page="/embedded/login.htm" authentication-failure-url="/embedded/login.htm?error=true" default-target-url="/embedded/login-embedded.html" /> <logout logout-success-url="/embedded/index.html"/> </http> <http auto-config="true" use-expressions="true" access-denied-page="/login.htm"> <intercept-url pattern="/login-success.html" access="hasRole('ROLE_AUTHENTICATED')"/> <intercept-url pattern="/**" access="permitAll"/> <form-login login-page="/login.htm" authentication-failure-url="/login.htm?error=true" default-target-url="/login-success.html"/> <logout logout-success-url="/index.html"/> </http> ``` I POST data to a Spring MVC controller which calls a service to validate a captcha. If that passes it forwards it to the `j_spring_security_check` RequestDispatcher. Here is the relevant part of the controller: ``` @RequestMapping(value ="/embedded/login.htm", method = RequestMethod.POST) public String authenticateCaptcha(HttpServletRequest request, HttpServletResponse response, @RequestParam String verificationText) throws IOException, ServletException { HttpSession session = request.getSession(); String sessionId = session.getId(); if (captchaService.validate(sessionId, verificationText)) { request.getRequestDispatcher("/j_spring_security_check").forward(request, response); return null; } return buildErrorRedirect(request); } ``` My problem is that after captcha is validated and the request is forwarded to Spring Security and authentication fails there the error page it forwards to is `/login.htm?error=true` instead of `/embedded/login.htm?error=true`.
