- Classname:
org.eclipse.jetty.servlets.CrossOriginFilter - Maven Artifact: org.eclipse.jetty:jetty-servlets
- Javadoc: http://www.eclipse.org/jetty/javadoc/9.4.12.v20180830/org/eclipse/jetty/servlets/CrossOriginFilter.html
HTTP requests made from a script are subject to well known restrictions, the most prominent being the same domain policy.
Firefox 3.5 introduced support for W3C’s Access Control for Cross-Site Requests specification, which requires a compliant client (for example, Firefox 3.5) and a compliant server (via this servlet filter).
This filter implements the required bits to support the server-side contract of the specification, and will allow a compliant client to perform cross-domain requests via the standard XMLHttpRequest object. If the client does not issue a compliant cross-domain request, this filter does nothing, and its overhead is the check of the presence of the cross-domain HTTP header.
This is extremely useful in CometD web applications where it is now possible to perform cross-domain long polling without using script injection (also known as the JSONP transport), and therefore removing all the downsides that the JSONP transport has (it’s chattier, does not react quickly to failures, has a message size limit, uses GET instead of POST, etc.).
You will need to put the jetty-servlets.jar file onto your classpath. If you are creating a webapp, ensure that this jar is included in your webapp’s WEB-INF/lib. Or, if you are running Jetty embedded you will need to ensure that jetty-servlets.jar is on the execution classpath. You can download the jetty-servlets.jar from the Maven Central Repository at https://repo1.maven.org/maven2/org/eclipse/jetty/jetty-servlets/. It is also available as part of the Jetty distribution in the $JETTY_HOME/lib directory.
This is a regular servlet filter that must be configured in web.xml.
It supports the following configuration parameters:
- allowedOrigins
- A comma separated list of origins that are allowed to access the resources. Default value is: * (all origins)
- allowedMethods
- A comma separated list of HTTP methods that are allowed to be used when accessing the resources. Default value is: GET,POST,HEAD
- allowedHeaders
- A comma separated list of HTTP headers that are allowed to be specified when accessing the resources. Default value is: X-Requested-With,Content-Type,Accept,Origin
- allowCredentials
- A boolean indicating if the resource allows requests with credentials. Default value is: true
- preflightMaxAge
- The number of seconds that preflight requests can be cached by the client. Default value is 1800 seconds (30 minutes)
- chainPreflight
- If true preflight requests are chained to their target resource for normal handling (as an OPTION request). Otherwise the filter will response to the preflight. Default is true.
- exposedHeaders
- A comma separated list of HTTP headers that are allowed to be exposed on the client. Default value is the empty list.
A typical configuration could be:
<web-app>
<filter>
<filter-name>cross-origin</filter-name>
<filter-class>org.eclipse.jetty.servlets.CrossOriginFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>cross-origin</filter-name>
<url-pattern>/cometd/*</url-pattern>
</filter-mapping>

/**
* <p>Implementation of the
* <a href="http://www.w3.org/TR/cors/">cross-origin resource sharing</a>.</p>
* <p>A typical example is to use this filter to allow cross-domain
* <a href="http://cometd.org">cometd</a> communication using the standard
* long polling transport instead of the JSONP transport (that is less
* efficient and less reactive to failures).</p>
* <p>This filter allows the following configuration parameters:
* <ul>
* <li><b>allowedOrigins</b>, a comma separated list of origins that are
* allowed to access the resources. Default value is <b>*</b>, meaning all
* origins.<br />
* If an allowed origin contains one or more * characters (for example
* http://*.domain.com), then "*" characters are converted to ".*", "."
* characters are escaped to "." and the resulting allowed origin
* interpreted as a regular expression.<br />
* Allowed origins can therefore be more complex expressions such as
* https?://*.domain.[a-z]{3} that matches http or https, multiple subdomains
* and any 3 letter top-level domain (.com, .net, .org, etc.).</li>
* <li><b>allowedMethods</b>, a comma separated list of HTTP methods that
* are allowed to be used when accessing the resources. Default value is
* <b>GET,POST</b></li>
* <li><b>allowedHeaders</b>, a comma separated list of HTTP headers that
* are allowed to be specified when accessing the resources. Default value
* is <b>X-Requested-With</b></li>
* <li><b>preflightMaxAge</b>, the number of seconds that preflight requests
* can be cached by the client. Default value is <b>1800</b> seconds, or 30
* minutes</li>
* <li><b>allowCredentials</b>, a boolean indicating if the resource allows
* requests with credentials. Default value is <b>false</b></li>
* </ul></p>
* <p>A typical configuration could be:
* <pre>
* <web-app ...>
