+<section name="CORS Filter">
+ <subsection name="Introduction">
+ <p>This filter is an implementation of W3C's CORS (Cross-Origin Resource
+ Sharing) <a href="http://www.w3.org/TR/cors/";>specification</a>, which is a
+ mechanism that enables cross-origin requests.</p>
+ <p>The filter works by adding required <code>Access-Control-*</code>
headers
+ to HttpServletResponse object. The filter also protects against HTTP
+ response splitting. If request is invalid, or is not permitted, then
request
+ is rejected with HTTP status code 403 (Forbidden). A
+ <a href="../images/cors-flowchart.png">flowchart</a> that
+ demonstrates request processing by this filter is available.</p>
+ <p>The minimal configuration required to use this filter is:</p>

+ <attribute name="cors.allowed.origins" required="false">
+ <p>A list of <a href="http://tools.ietf.org/html/rfc6454";>origins</a>
+ that are allowed to access the resource. A <code>*</code> can be
+ specified to enable access to resource from any origin. Otherwise, a
+ whitelist of comma separated origins can be provided. Eg: <code>
+ http://www.w3.org, https://www.apache.org</code>.
+ <strong>Defaults:</strong> <code>*</code> (Any origin is allowed to
+ access the resource).</p>
+ </attribute>
+ <attribute name="cors.allowed.methods" required="false">
+ <p>A comma separated list of HTTP methods that can be used to access
the
+ resource, using cross-origin requests. These are the methods which will
+ also be included as part of <code>Access-Control-Allow-Methods</code>
+ header in pre-flight response. Eg: <code>GET, POST</code>.
+ <strong>Defaults:</strong> <code>GET, POST, HEAD, OPTIONS</code></p>
+ </attribute>
+ <attribute name="cors.allowed.headers" required="false">
+ <p>A comma separated list of request headers that can be used when
+ making an actual request. These headers will also be returned as part
+ of <code>Access-Control-Allow-Headers</code> header in a pre-flight
+ response. Eg: <code>Origin,Accept</code>. <strong>Defaults:</strong>
+ <code>Origin, Accept, X-Requested-With, Content-Type,
+ Access-Control-Request-Method,
Access-Control-Request-Headers</code></p>
+ </attribute>
+ <attribute name="cors.exposed.headers" required="false">
+ <p>A comma separated list of headers other than simple response headers
+ that browsers are allowed to access. These are the headers which will
+ also be included as part of <code>Access-Control-Expose-Headers</code>
+ header in the pre-flight response. Eg:
+ <code>X-CUSTOM-HEADER-PING,X-CUSTOM-HEADER-PONG</code>.
+ <strong>Default:</strong> None. Non-simple headers are not exposed by
+ default.</p>
+ </attribute>
+ <attribute name="cors.preflight.maxage" required="false">
+ <p>The amount of seconds, browser is allowed to cache the result of the
+ pre-flight request. This will be included as part of
+ <code>Access-Control-Max-Age</code> header in the pre-flight response.
+ A negative value will prevent CORS Filter from adding this response
+ header to pre-flight response. <strong>Defaults:</strong>
+ <code>1800</code></p>
+ </attribute>
+ <attribute name="cors.support.credentials" required="false">
+ <p>A flag that indicates whether the resource supports user
credentials.
+ This flag is exposed as part of
+ <code>Access-Control-Allow-Credentials</code> header in a pre-flight
+ response. It helps browser determine whether or not an actual request
+ can be made using credentials. <strong>Defaults:</strong>
+ <code>true</code></p>
