When a plaintext request goes through an HTTP proxy, requestUri() builds the absolute-form request target with Uri.toUrl(), which embeds the userinfo, so a request for http://user:secret@origin.example.com/resource sends those credentials to the proxy in the clear on the request line and into its access log. RFC 9110 section 4.2.4 says a sender must not generate the userinfo subcomponent when a request target is built. The sibling paths already comply: CONNECT uses getAuthority(), the Host header comes from hostHeader(uri), and the HTTP/2 path runs stripUserInfo() before setting :authority, so only the HTTP/1.1 absolute-form branch was missed. Kept toUrl() and the caller-visible Request.getUrl() unchanged and added a variant that omits the userinfo, with a test that fails on the current request line.
