+<code lua>
+function main (userId)
+    INFO("Doing CURL");
+  str = ''
+  c = cURL.easy_init()
+  c:setopt_url("http://192.168.1.230:8000")
+  c:setopt_timeout(15)
+  c:setopt{[cURL.OPT_CUSTOMREQUEST] = "PUT"}  -- this is custom method
+  c:setopt{
+        [cURL.OPT_POSTFIELDS] = 'Content-type: text/html'
+  }
+  c:post({'THIS IS CONTENT OF THE PUT'})
+  c:perform({writefunction = function(res) str = res end })
+  c:close()
+  INFO("CURL done\n" .. str);
