If the application takes responsibility for setting the chunked encoding header it also has to take responsibility sending for a correctly encoded body. Generally, it is much simpler to let the container handle chunked encoding.

Even If I change the body into a simple character or other string, it also damaged.How can I solve this problem ? I just send a simple character is it not a correctly body?and It worked well when I use jetty or undertow, when I remove the header "connetion:close", it also worked well. Have I do some illegal operation?
