PaulS:
www.fastrprint(F("GET "));
www.fastrprint(WEBPAGE);
www.fastprint(Temp);
www.fastrprint(F(" HTTP/1.1\r\n"));
will send the GET statement (and space), the script name and value identifier, and the Temp variable's contents,m and the HTTP part in 4 packets, which is not ideal, but uses the least amount of memory. It is hardly less efficient than sending just 3 packets.
This is what I recommend that you do.
Thank you. I tried this:
www.fastrprint(F("GET "));
www.fastrprint(WEBPAGE);
www.fastrprint(Temp);
www.fastrprint(F(" HTTP/1.1\r\n"));
www.fastrprint(F("Host: ")); www.fastrprint(WEBSITE); www.fastrprint(F("\r\n"));
www.fastrprint(F("\r\n"));
www.println();
But then i get this error below and it points out this row: www.fastrprint(Temp);

Do i need to convert Temp to something else perhaps?
