This also removed the CsrfToken from the response headers to prevent the
token from being saved. If user's wish to return the CsrfToken in the
response headers, they should use the CsrfToken found on the request.
Previously AbstractSecurityWebApplicationInitializer delegated to a
WebApplicationInitializer, but it caused issues in some instances where
a container would pass the annonymous inner class to
SpringServletContainerInitializer which caused errors on startup.
Now AbstractSecurityWebApplicationInitializer registers the
ContextLoaderListener on its own instead of delegating.
Added JavaConfig for Headers. In the process, more HeaderWriter instances
were added so that we can reuse logic between the XML and JavaConfig. This
also prompted repackaging the writers.
This is a distinct filter as apposed to reusing StaticHeaderWriter
since the specification specifies that the "Strict-Transport-Security"
header should only be set on secure requests. It would not make sense to
require DelegatingRequestMatcherHeaderWriter since this requirement is
in the specification.
- hf.doFilter is missing FilterChain argument
- response.headers does not contain the exact values for the headers so
should not be used for comparison (note it is a private member so this
is acceptable)
- hf does not need non-null check when hf.doFilter is invoked
- some of the configurations are no longer valid (i.e. ALLOW-FROM
requires strategy)
- Some error messages needed updated (some could still use improvement)
- No validation for missing header name or value
- rebased off master / merged
- nsa=frame-options-strategy id should use - not =
- FramewOptionsHeaderFactory did not produce "ALLOW-FROM " prefix of origin
- remove @Override on interface overrides to work with JDK5
- Implemented different ALLOW-FROM strategies as specified in the proposal.

config/src/main/java/org/springframework/security/config/http/HeadersBeanDefinitionParser.java
config/src/test/groovy/org/springframework/security/config/http/HttpHeadersConfigTests.groovy
Created HeadersFilter for setting security headers added including a
bean definition parser for easy configuration of the headers. Enables
easy configuration for the X-Frame-Options, X-XSS-Protection and
X-Content-Type-Options headers. Also allows for additional headers to
be added.
Session fixation protection, whether by clean new session or
migrated session, now publishes an event when a session is
migrated or its ID is changed. This enables application developers
to keep track of the session ID of a particular authentication
from the time the authentication is successful until the time
of logout. Previously this was not possible since session
migration changed the session ID and there was no way to
reliably detect that.
Revised changes per Rob Winch's suggestions.
Previously Spring Security would disable automatically saving the
SecurityContext when the Thread was different than the Thread that
created the SaveContextOnUpdateOrErrorResponseWrapper. This worked for
many cases, but could cause issues when a timeout occurred. The problem
is that a Thread can be reused to process the timeout since the Threads
are pooled. This means that a timeout of a request trigger an apparent
logout as described in the following workflow:
- The SecurityContext was established on the SecurityContextHolder
- An Async request was made
- The SecurityContextHolder would be cleared out
- The Async request times out
- The Async request would be dispatched back to the container upon
timing out. If the container reused the same Thread to process the
timeout as the original request, Spring Security would attempt to
save the SecurityContext when the response was committed. Since the
SecurityContextHolder was still cleared out it removes the
SecurityContext from the HttpSession
Spring Security will now prevent the SecurityContext from automatically
being saved when the response is committed as soon as
HttpServletRequest#startAsync() or
ServletRequest#startAsync(ServletRequest,ServletResponse) is called.
