I have an embedded device running a slimmed down version of a HTTP server. Currently, it can display static HTML pages. Here is an example of how it displays a static HTML page:
char *text="HTTP/1.0 200 OK\r\nContent-Type: text/html\r\n\r\n" "<html><body>Hello World!</body></html>"; IPWrite(socket, (uint8*)text, (int)strlen(text)); IPClose(socket);
What I'd like to do is display dynamic content, e.g. a reading from a sensor. What I thought of so far is to have the page refresh every once in awhile with
<meta http-equiv="refresh" content="600">
and use sprintf() to attach the sensor reading to the text variable for the response.
Is there a way I can do this without having to refresh the page constantly?
