Access-Control-Allow-Origin: 500 Internal Error

Question

So I am trying to have siteA do a jquery .load of some content on siteB. In doing this, im getting the Access-Control-Allow-Origin Error. So on siteB, I placed a .htaccess file that should allow siteA to be able to grab content from it. I am running into some trouble with this. I know the .htaccess file is being access because it is getting a 500 Internal Error when the page tries to load and i have content in the .htaccess file.

In the .htaccess file i have tried: Access-Control-Allow-Origin: * and: Access-Control-Allow-Origin: "*"

but both give the 500 error. I have also tried: Access-Control-Allow-Origin: *

This doesn't give the 500 error, so it must be coming back as false. I am not really sure what to do at this point. its possible i might be formatting the .htaccess file wrong or something, but i think it may have to do with mod_headers not being enabled.

In Logs: Invalid command 'Access-Control-Allow-Origin:', perhaps misspelled or defined by a module not included in the server configuration

Both sites are running through 10.8 Server.app, so its a little different from a normal Apache install which is making it a little difficult. Any help would be greatly appreciated! Thanks in advance!

Answer 1

In my case, I have copied code from somewhere, which is having some spaces, that was the reason for internal server error.

I was using

header("Access-Control-Allow-Origin : *");

We should write

header("Access-Control-Allow-Origin:*");

I have just removed spaces between Origin, :, and *

Try writing the code instead of copy, that may help.

Answer 2

I was just having the same issue, error 500 when I used:

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

It was due to a missing module , mod_headers , I just had to run on my server:

sudo a2enmod headers

as found here

but i think you may need to edit manually .conf on OSX and uncomment the line:

#LoadModule headers_module modules/mod_headers.so
