Hi I have filled a bug report for a problem with Cookie in HttpClient and following bug was opened now:
Issue: https://bugs.openjdk.java.net/browse/JDK-8276774 Proposal to solve the problem for Http/1.1: * Class jdk/internal/net/http/Http1Request.java, Method collectHeaders0 * Replace line 112 with: HttpHeaders filteredSystemHeaders = HttpHeaders.of(systemHeaders.map(), (k,v) -> uh.firstValue(k).isEmpty()); * Replace line 118 with: collectHeaders1(sb, filteredSystemHeaders, nocookies); The idea is that the line 127: "collectCookies(sb, systemHeaders, userHeaders);" will then use the real system headers containing the Cookie header with the cookies from the CookieManager, and so we should collect both cookies from userHeaders and from systemHeaders together. Could someone please check this and perform the fix ? Note that the same problem probably impacts the HTTP/2 implementation as the same filter is used in jdk.internal.net.http.Stream.headerFrame(long) at line 658 sysh = HttpHeaders.of(sysh.map(), (k,v) -> uh.firstValue(k).isEmpty()); So we should check this case, too.
