I keep seeing this word pragma. What does it mean?

Projects Programming

and yes I have googled, and because it shows up in different places, I can't even tell if it is verb noun or other.

Just one example:

void handleNewsConfigure() {
if (!athentication()) {
return server.requestAuthentication();
}
digitalWrite(externalLight, LOW);

server.sendHeader("Cache-Control", "no-cache, no-store");
server.sendHeader("Pragma", "no-cache");
server.sendHeader("Expires", "-1");
server.setContentLength(CONTENT_LENGTH_UNKNOWN);
server.send(200, "text/html", "");

sendHeader();

see Directive (Programming)

See this: Pragma - HTTP | MDN

It has nothing to do with the #pragma C/C++ preprocessor directive

Ok thanks. Essentially multiple definitions and multiple uses under one or more of those definitions. Laughing as he types this.
