[OpenLayers-Dev] WFS without proxy

[Andreas Hocevar]

Hi Steven,

for this to work, your server has to provide the correct response to the OPTIONS request that the browser sends to determine whether the server allows cross-domain access. OpenLayers is not involved in this OPTIONS request.

At this points, I am not aware of any WFS that supports HTTP access control.

If you are able to proxy the WFS in questions through your httpd, you can either bring your WFS to your web site's domain [1], or configure the httpd to send the HTTP access control response.

Regards,
Andreas.

There is a new feature introduced in firefox and other modern browsers which should allow for cross-site XHRequests (https://developer.mozilla.org/en/HTTP_access_control).

I'm at a loss why this is, I've put a breakpoint in /lib/openlayers/Request.js at the OPTIONS function, but it is never called and nowhere else in openlayers code there is a mention of OPTIONS requests.
