CouchDB cross domain access from web

This answer is assuming that you have an actual Domain account that you are able to authenticate with. I'm not familiar with this exact issue, but on the program you are trying to open, you may be able to SHIFT + Right-Click and select Run As. Then type your DOMAIN\Username as the username and your network password. This should be the same as your VPN domain, username, and password.

This error is returned by your browser.

Basically means you just can't do that.

CORS related headers should not be set in Apache (in your case)

Generate that in your NodeJS application with specified domain:port, not wildcard.

Here's a similar case you may want to have a look

I don't know NodeJS. In php you can use

header("Access-Control-Allow-Origin: ".$_SERVER['HTTP_ORIGIN']);

to simulate wildcard.
