Apache Solr: Setting HTTP Response Headers From solrconfig.xml For CORS

Is it possible to setup the sending of a custom HTTP response header from within the

solrconfig.xml

file? I am thinking that it might be possible to add some configuration to the

<requestDispatcher>

section since it controls caching headers.

I am sure this is possible in the servlet container configuration (Jetty, Tomcat, etc.), but I would like to do this from within Solr's configuration files if at all possible.

If this makes any difference, I am attempting to set an

Access-Control-Allow-Origin

header for CORS AJAX requests from a different host.

You could use JSONP instead. See this link for an example
