Re: [jetty-users] Configuring option 2 of RFC 7230 paragraph 5 (HTTP header folding)
You are still seeing "400 Header Folding".
That's only seen during the 7230 compliance mode.

https://github.com/eclipse/jetty.project/blob/jetty-9.3.16.v20170120/jetty-http/src/main/java/org/eclipse/jetty/http/HttpParser.java#L1003-L1004

The 2616 compliance mode wasn't set for that connector.

Hi Joakim,

Have you tried the HttpCompliance.RFC2616 mode in Jetty?

 since I wasn't aware of that, no ;-)

https://github.com/eclipse/jetty.project/blob/jetty-9.3.16.v20170120/jetty-server/src/main/config/etc/jetty-http.xml#L32

Set the property `jetty.http.compliance=RFC2616` and try again.

 I set the configuration first by setting it in a static block within my classes and
after that as property being set as run-conguration. Both tries failed. Here some
code how I set that up:

                System.out.println("Starting HTTP-server with comliance setting: " + System.getProperty("jetty.http.compliance"));
                Server hs = new Server();
                ServerSocket ss = new ServerSocket(0);
                LISTEN_PORT = ss.getLocalPort();
                ss.close();
                hs.setServerName("testserver"+LISTEN_PORT);
                assertNotNull("check existance of testserver", Server.getServer("testserver"+LISTEN_PORT));
                ServerConnector sconn = new ServerConnector(hs, new ConnectionFactory[]{
                        new HttpConnectionFactory(),
                });
                sconn.setPort(LISTEN_PORT);
                hs.addConnector(sconn);
                assertNotNull("check existance of testserver after second call", Server.getServer("testserver"+LISTEN_PORT));
                ContextHandlerCollection coll = new ContextHandlerCollection();
                hs.setHandler(coll);
                hs.start();

                [...]

Server is a class derived by me from the jetty-Server-class providing the
method getServer(String) in case you wonder.

These are the logs given out (plus some debug-text outputted by my testcase:

The request is a fixed text in the testcase in case you wonder about the Date.
The debug output shows that the system property is really set but it seems
to be ignored.



Thanks and cheers, Lothar
