Add a parameter that limits sending Basic authentication in the Authorization header to only the first host and not any that we're redirected to. Ignoring potential security concerns, temporary AWS URLs will reject any request that includes authentication details in both the query parameters (from the redirect) and in the Authorization header. Temporary AWS URLs are now being used for release assets from private Github repositories. According to the previous discussion linked below, they're also in use by bitbucket.
