cross domain - If block for specific url .htaccess -

i have little problem here

<ifmodule mod_headers.c>     header append access-control-allow-origin "*" </ifmodule>

you can use mod_setenvif this:

setenvifnocase request_uri ^/ajax/wigdet ajax  header append access-control-allow-origin "*" env=ajax
