Enable CORS

I have recompiled apache to include the headers module and it worked fine.
But when I add
Header set Access-Control-Allow-Origin "*"
to the httpd.conf file, nothing changes?
I still can't get cors enabled.

thanks

can you provide the full paths of the files which you are editing, this is very important?

I'm wanting to enable CORs too.. But Mod_headers isn't included in apache, and I'm having the hardest trouble trying to add that module somehow.

I'm basically wanting to be able to put this in the vhosts or httpd.conf
<IfModule mod_headers.c>
    Header set Access-Control-Allow-Origin: *
</IfModule>

But apache doesn't have mod_headers.c

so I search for it and make a file and paste the contents of mod_headers.c
I then do
/usr/local/apache/bin/apxs -c mod_headers.c

To try adding it to apache and it goes through some of the process, but stops with a bunch of errors

Headers nowhere to be found. I'd appreciate any help to get this working so I can add headers again, via vhosts, httpd.conf, and htaccess

you should use apache rebuilder tool to rebuild apache with additional required mods.
