[OpenLayers-Dev] WFS without proxy

[Steven M. Ottens]

  Hi all,

I'm trying to get WFS POST-requests working in openlayers without a 
proxy. (The reason for that is that I want to get shiboleth 
authentication working, which doesn't allow for proxies). 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).

However when I remove the proxy from the configuration openlayers does 
an HTTP OPTIONS request to the WFS server, instead of a POST request. 
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.

Has anyone tried (and succeeded) to use openlayers and POST requests 
without a proxy and/or know why there is a OPTIONS request?

regards,
Steven
