javascript - Cross-origin resource sharing for Tomcat 5.5 -

-

i new cross-origin resource sharing , want enable in tomcat 5.5 server. can give me hint how can achieved?

i want set header universally requests, , allow origins (access-control-allow-origin: *)

if it's static site, starting tomcat 7.0.41, can control cors behavior via built-in filter.

pretty thing have edit global web.xml in catalina_home/conf , add filter definition:

      <!-- ================== built in filter definitions ===================== -->        ...       <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>      <!-- ==================== built in filter mappings ====================== -->

be aware, though, firefox not access-control-allow-origin: * , requests credentials (cookies): when responding credentialed request, server must specify domain, , cannot use wild carding.
