Re: [Openstack] Nova middleware for enabling CORS?
Since the CORS support in Swift allows the preflight OPTIONS response to be different on a per-container basis (which is correct in a multi-tenant system), the CORS support was added directly into Swift's proxy server rather than as middleware. In order to fulfill the OPTIONS request, container information needs to be read from the system, and the proxy server already has this information (probably in cache). Implementing the CORS support as middleware would require duplicating much of the code and framework that already exists in Swift's proxy server. CORS support in Swift was correctly implemented. --John On Oct 30, 2012, at 10:57 AM, Renier Morales wrote: > On Oct 30, 2012, at 1:08 PM, David Kranz wrote: > >> On 10/30/2012 12:43 PM, Renier Morales wrote: >>> Hello, >>> >>> I'm wondering if someone has already created a nova paste filter/middleware >>> for enabling Cross-Origin Resource Sharing (CORS), allowing a web page to >>> access the openstack api from another domain.

Keystone doesn't (yet) support CORS - there's an open blueprint for it, but no work has been applied there as yet -joe On Oct 30, 2012, at 10:57 AM, Renier Morales wrote: > On Oct 30, 2012, at 1:08 PM, David Kranz wrote: > >> On 10/30/2012 12:43 PM, Renier Morales wrote: >>> Hello, >>> >>> I'm wondering if someone has already created a nova paste filter/middleware >>> for enabling Cross-Origin Resource Sharing (CORS), allowing a web page to >>> access the openstack api from another domain.

Should other services (nova, keystone, glance) do the same kind of intrinsic CORS enablement? It's surprising that something like CORS, if done, would not be done in a more generic plug-in friendly that you could use across all services. -Renier ___ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp
Re: [Openstack] Nova middleware for enabling CORS?
Javier, Thank you. That sounds good. Actually I would only need to enable CORS on Nova, Keystone, and Glance. So if you have that and can share it, that would be perfect for me. Awesome actually :-) Thanks, -Renier On Oct 30, 2012, at 1:08 PM, javier cerviño wrote: > Hi Renier, > > We're currently developing a JavaScript API for Nova, Keystone, and > Glance.

Re: [Openstack] Nova middleware for enabling CORS?
Hi Renier, We're currently developing a JavaScript API for Nova, Keystone, and Glance. To do so we also installed a CORS filter, developed by Adrian Smith, (with small changes) in these components. I can pass you the code and a short guideline to configure it if you want. Cheers, Javier.
