ES8266 convert ESP8266webserver to ESPAsyncWebServer

[Newsoftman]

Good day

I am very new in this forum.

I realized a small project using the ES8266 and the ESPAsyncWebServer to control a couple of relays.

I created a web page that has the push buttons which change their color when the relevant relay is On or OFF.

I used the follwing line of code to auto refresh the page:

webPage ="<meta http-equiv='refresh' content='5'>";

The page update is working well but there is a problem because when the page is update the Browser send to the server the command that was last activated.

The relay comes ON and OFF at 5 secs rate !(e.g: the browser sends:” 192.169.1.80/relay1 “that toggles the relay state).

In the past I used the ESP8266webserver.h and the following line of code instructed the browser to engage the wanted IP with no command :

server.sendHeader("Location",String ("http://")+"192.168.1.80",true);

Could you please indicate to me the equivalent code to be used with ESPsyncWebServer ?

Thanks in advance for any reply / help .
Bye

Hi Newsoftman,
I think you must attach your code to help you.
ESPsyncWebServer uses the response to add the header, so if you post your code we tell you the correct position.

response->addHeader("Location",String ("http://")+"192.168.1.80");

I think you can find some information also here
Web server with esp8266 and esp32: multi purpose generic web server – 3

There is the ESP8266webserver and ESPAsyncWebServer implementation.

Bye Renzo

thanks a lot for the assistance: I found the following :
request->redirect("http://192.168.1.80");
It is working fine.
Bye
