+# Simple HTTPD Server Example
+
+The Example consists of HTTPD server demo with demostration of URI handling :
+    1. URI \hello for GET command returns "Hello World!" message
+    2. URI \echo for POST command echoes back the POSTed message
+
+* Open the project configuration menu (`idf.py menuconfig`) to configure Wi-Fi or Ethernet. See "Establishing Wi-Fi or Ethernet Connection" section in [examples/protocols/README.md](../../README.md) for more details.
+
+* In order to test the HTTPD server persistent sockets demo :
+    1. compile and burn the firmware `idf.py -p PORT flash`
+    2. run `idf.py -p PORT monitor` and note down the IP assigned to your ESP module. The default port is 80
+    3. test the example :
+        * run the test script : "python scripts/client.py \<IP\> \<port\> \<MSG\>"
+            * the provided test script first does a GET \hello and displays the response
+            * the script does a POST to \echo with the user input \<MSG\> and displays the response
+        * or use curl (asssuming IP is 192.168.43.130):
+            1. "curl 192.168.43.130:80/hello"  - tests the GET "\hello" handler
+            2. "curl -X POST --data-binary @anyfile 192.168.43.130:80/echo > tmpfile"
+                * "anyfile" is the file being sent as request body and "tmpfile" is where the body of the response is saved
+                * since the server echoes back the request body, the two files should be same, as can be confirmed using : "cmp anyfile tmpfile"
+            3. "curl -X PUT -d "0" 192.168.43.130:80/ctrl" - disable /hello and /echo handlers
+            4. "curl -X PUT -d "1" 192.168.43.130:80/ctrl" -  enable /hello and /echo handlers
+
+See the README.md file in the upper level 'examples' directory for more information about examples.
