Permitir CORS en Apache / Enable CORS on Apache

To add the CORS authorization to the header using Apache, simply add the following line inside either the <Directory>, <Location>, <Files> or <VirtualHost> sections of your server config (usually located in a *.conf file, such as httpd.conf or apache.conf), or within a .htaccess file:

  Header set Access-Control-Allow-Origin "*"

To ensure that your changes are correct, it is strongly reccomended that you use

apachectl -t

to check your configuration changes for errors. After this passes, you may need to reload Apache to make sure your changes are applied by running the command

sudo service apache2 reload

or

apachectl -k graceful

.

Altering headers requires the use of mod_headers. Mod_headers is enabled by default in Apache, however, you may want to ensure it’s enabled by run

a2enmod headers

Note: you can also use add rather than set, but be aware that add can add the header multiple times, so it’s likely safer to use set.
