CORS on Tomcat

Apache Tomcat includes support for CORS (Starting from Tomcat version 7.0.41). The full documentation can be found here: http://tomcat.apache.org/tomcat-7.0-doc/config/filter.html#CORS_Filter

Here is an example from those docs that demonstrates a minimal CORS configuration:

<filter>
  <filter-name>CorsFilter</filter-name>
  <filter-class>org.apache.catalina.filters.CorsFilter</filter-class>
</filter>
<filter-mapping>
  <filter-name>CorsFilter</filter-name>
  <url-pattern>/*</url-pattern>
</filter-mapping>
