The HTTP server should be closing the connection once the last "zero-length" 
chunk is sent.  You should check which side is closing the socket (i.e. use 
tcpdump or wireshark).  You should also check if the server is first 
responding with status "100 Continue.", it shouldn't since LuaSocket doesn't 
send the "Expect: 100-continue" header.

You could also try the http client library in my lua-handlers [1] project.  I 
have uploaded a http client PUT example [2], that does the same thing as your 
code.
