Set Apache headers conditionally

I'm working with an apache server, and I'd like to add headers conditionally.

If the URI matches a certain regex, I'd like to add the header Access-Control-Allow-Origin: *. What is a good way to do this?

What I've tried so far:

  1. I added code called by the request handler, using apr_table_add(rq->headers_out, "Access-Control-Allow-Origin", "*"). But it seems like Apache strips the header before sending the response whenever the header Content-Type: application/x-javascript is also set. Is this the wrong way to do it? Why would Apache strip the header?

  2. I've heard mod_headers suggested. Does mod_headers have the capability to place headers based on regex matching with the request URI?

Solution 
  • SetEnvIf Request_URI somepartofurl SIGN
Header always add "Access-Control-Allow-Origin" "*" env=SIGN

    but this works only if located in the configuration. Placing it into .htaccess won't help.
