It is the browser that forms the "Authorization" header. The apache proxy simply forwards the header (along with all the other headers in the request) to the backend server. If you don't want to pass this header in the proxy-backend network, you could protect the realm in the proxy and have it open in the backend; eg: In proxy: <Location /path/to/realm> Auth directives Require valid-user </Location> ProxyPass /path/to/realm http://backend-server ProxyPassReverse /path/to/realm http://backend-server In backend: - remove Auth directives Rgds, Owen Boyle Disclaimer: Any disclaimer attached to this message may be ignored. > > In case it cannot be configured: Which module of apache > handles setting > the authorization header?
