Turning on Tomcat's RequestDumper causes problem with web co

[edikus]

I am using JBoss4.0.1sp1 with the default Tomcat bundle. In the process of trying to debug a problem with a test engine, I turned on the RequestDumperValve in server.xml. After that, the applet gets an error after starting:

Put in your client:

HttpURLConnection conn;
conn.setRequestProperty("Transfer-Encoding", "chunked");
conn.setChunkedStreamingMode(-1);
