Problem Description
When using mDNS_Web_Server
I got an empty reply from server
curl -v "http://esp32.local/"
* Trying 192.168.1.23...
* TCP_NODELAY set
* Connected to esp32.local (192.168.1.23) port 80 (#0)
> GET / HTTP/1.1
> Host: esp32.local
> User-Agent: curl/7.64.1
> Accept: */*
>
* Empty reply from server
* Connection #0 to host esp32.local left intact
curl: (52) Empty reply from server
* Closing connection 0
If I remove the client.flush() call here https://github.com/esp8266/Arduino/blob/master/libraries/ESP8266mDNS/examples/mDNS_Web_Server/mDNS_Web_Server.ino#L106
and add a client.stop() at the end of the loop.
all is working fine.
curl -v "http://esp32.local/"
* Trying 192.168.1.23...
* TCP_NODELAY set
* Connected to esp32.local (192.168.1.23) port 80 (#0)
> GET / HTTP/1.1
> Host: esp32.local
> User-Agent: curl/7.64.1
> Accept: */*
>
< HTTP/1.1 200 OK
< Content-Type: text/html
* no chunk, no close, no size. Assume close to signal end
<
<!DOCTYPE HTML>
<html>Hello from ESP32 at 192.168.1.23</html>
* Closing connection 0
I am not sure if it's a bug or not but it seems legit to me not to flush the client and just stop the connection.
