Hello :) I use this library well.

but want to know that on /wifisave page,
I want user to know if they enter ssid and password correctly,

for now,
when users enter ssid / password on /wifi page,
it redirect to page according to below code no matter password is correct or incorrect.
but I want to alert user if password is incorrect.

is it possible?
On connectWifi function, when connRes is 4 , it is password incorrect . I wonder it can trigger alert or alert page. and how.

server->sendHeader("Cache-Control", "no-cache, no-store, must-revalidate");
server->sendHeader("Pragma", "no-cache");
server->sendHeader("Expires", "-1");
server->setContentLength(CONTENT_LENGTH_UNKNOWN);
server->send(200, "text/html", ""); // Empty content inhibits Content-length header so we have to close the socket ourselves.

String head = FPSTR(HTTP_HEAD);
head.replace("{v}", "Credentialsdddddd Saved");
server->sendContent(head);
server->sendContent_P(HTTP_SCRIPT);
server->sendContent_P(HTTP_STYLE);
server->sendContent_P(HTTP_HEAD_END);

server->sendContent_P(HTTP_SAVED);

server->sendContent_P(HTTP_END);
server->client().stop();

@tzapu @tablatronix
Any update on this? Because if user enters ssid/psk incorrectly by mistake, it goes into a mode where user gets confused what to do ahead and they are not aware if they entered it correctly or not.
