Re: CORS configuration in HTTP Service

[Ben Fortuna]

I have implemented this before in AEM, we added the configuration to the
Apache/Dispatcher in front of AEM, which may be the simplest approach if
you are using Apache also.

Hi,

Created filter service, which works fine, but isn’t there an easier
(configuration) option ?

Thanks

Subject:  CORS configuration in HTTP Service

Hi team,

I like to configure CORS (Cross Origin Requests) by always returning the
following http parameter

Access-Control-Allow-Origin: *

in the response. One option is to write a http filter server that adds the
parameter, but this is quite a bit of work for adding a simple parameter.
Jetty supports that kind of configuration in web.xml but I think web.xml is
not working under Felix http.

Any easy way to add a http parameter to each response of each http server?
Thanks
Frank
