Hello all,
Experimenting http tunneling with org.apache.http.impl.client.ProxyClient with
Apache 2.2 configured as a direct proxy.
Code is just the same as org.apache.http.examples.client.ProxyTunnelDemo.java :
ProxyClient proxyClient = new ProxyClient();
HttpHost target = new HttpHost("mytargetserver ", 443);
HttpHost proxy = new HttpHost("localhost", 8080);
UsernamePasswordCredentials credentials = new
UsernamePasswordCredentials("user", "pwd");
Socket socket = proxyClient.tunnel(proxy, target, credentials);
Connection attempts are failing with code 502.
The client log :
[DEBUG] headers - http-outgoing-0 >> CONNECT mytargetserver:443 HTTP/1.1
[DEBUG] headers - http-outgoing-0 >> Proxy-Connection: Keep-Alive
[DEBUG] headers - http-outgoing-0 << HTTP/1.1 400 Bad Request
[DEBUG] headers - http-outgoing-0 << Date: Tue, 01 Oct 2013 12:32:33 GMT
[DEBUG] headers - http-outgoing-0 << Server: Apache/2.2.25 (Win32)
[DEBUG] headers - http-outgoing-0 << Content-Length: 226
[DEBUG] headers - http-outgoing-0 << Connection: close
[DEBUG] headers - http-outgoing-0 << Content-Type: text/html; charset=iso-8859-1
[DEBUG] DefaultManagedHttpClientConnection - http-outgoing-0: Close connection
The Host header is missing.
Confirmed by the error log on Apache server side :
Client sent HTTP/1.1 request without host name (see RFC2616 section 14.23)
I could fix this issue by adding a RequestTargetHost processor in
org.apache.http.impl.client.ProxyClient.java at line 112 :
this.httpProcessor = new ImmutableHttpProcessor(new
RequestTargetHost(), new RequestClientConnControl(), new RequestUserAgent());
instead of just
this.httpProcessor = new ImmutableHttpProcessor(new
RequestClientConnControl(), new RequestUserAgent());
I didn't see any way of changing the behavior of ProxyClient from the outside
so this really looks like a bug to me.
Anybody experimenting the same ?
Is there a better way of establishing http tunneling with HttpClient 4.3 ?
Should the issue be reported ?
Thanks
Valentin
