| summary: Sensitive headers incorrectly sent after cross-domain redirect in net/http |
| description: |- |
| The HTTP client drops sensitive headers after following a cross-domain redirect. |
| For example, a request to a.com/ containing an Authorization header which is |
| redirected to b.com/ will not send that header to b.com. |
| |
| In the event that the client received a subsequent same-domain redirect, |
| however, the sensitive headers would be restored. For example, a chain of |
| redirects from a.com/, to b.com/1, and finally to b.com/2 would incorrectly send |
| the Authorization header to b.com/2. |
