Hi Folks!

I just ran into a problem ... I'd like to access OpenStreetMap data
directly from a web application via a XMLHttpRequest. Unfortunately
cross-domain XMLHttpRequests are not allowed unless the foreign web server
replies with a special HTTP-header (Access-Control-Allow-Origin) and you
are using a modern browser (e.g. Firefox >=3).

Here you can find some documentation:

This is the needed HTTP-header-line:
Access-Control-Allow-Origin: *
(this would allow XMLHttpRequests from any client web browser)

Does anybody see a problem adding these HTTP-Header-line to the
OpenStreetMap-API and the Nominatim-API?
