Apache Solr – Enable CORS

Cross-Origin Resource Sharing

This is a blatant rip-off from Mariano Guerra’s Blog  on enabling CORS in Apache Solr amd he got it from Stack overflow but I look this up on a regular bases so now I added it to my own cheat-sheets. 🙂Add the following XML before the existing filter section in server/solr-webapp/webapp/WEB-INF/web.xml:

<filter>
    <filter-name>cross-origin</filter-name>
    <filter-class>org.eclipse.jetty.servlets.CrossOriginFilter</filter-class>
    <init-param>
         <param-name>allowedOrigins</param-name>
         <param-value>http://localhost*</param-value>
    </init-param>
     <init-param>
         <param-name>allowedMethods</param-name>
         <param-value>GET,POST,DELETE,PUT,HEAD,OPTIONS</param-value>
     </init-param>
     <init-param>
         <param-name>allowedHeaders</param-name>
         <param-value>origin, content-type, cache-control, accept, options, authorization, x-requested-with</param-value>
     </init-param>
    <init-param>
        <param-name>supportsCredentials</param-name>
        <param-value>true</param-value>
    </init-param>
    <init-param>
      <param-name>chainPreflight</param-name>
      <param-value>false</param-value>
    </init-param>
</filter>

<filter-mapping>
  <filter-name>cross-origin</filter-name>
  <url-pattern>/*</url-pattern>
</filter-mapping>
