Arduino Get request and host server?

Question

I am trying to have my arduino run a web server but also post a variable from time to time. I have the following code:

client.println("HTTP/1.1 200 OK");
client.println("Host: joeybabcock.me");    //
client.print("GET /writetemplocalserv.php?t0=");     
client.println("Content-Type: text/html");
client.println(sensorValue);
client.println("Connnection: close");

and the whole code here(It's quite a bit so only look through if you have to.): http://pastebin.com/TXPccYs3 This does not post the variable. if visited in the web browser to the exact same url, it does, however, work.

Is this a request or a response??? This is not valid HTTP. Read RFC2161 before throwing bytes to network. — LS_ᴅᴇᴠ

i need to submit a get request at the brginning of the program, than a standard response when a client connects. i have the standard response, just not the get request — joeybab3

RFC 2161, defining http/1.1, MUST always be followed when writing Web (HTTP) servers and clients.

Your code is a big mess:

client.println("HTTP/1.1 200 OK"); //Response
client.println("Host: joeybabcock.me"); //Response/request
client.print("GET /writetemplocalserv.php?t0="); //Request
client.println("Content-Type: text/html"); //Response
client.println(sensorValue); //Probably invalid...
client.println("Connnection: close"); //Request/Response

In a very, VERY, VERY brief way, if you want to request you do:

client.print("GET /writetemplocalserv.php?t0=");
client.print(sensorValue);
client.println(" HTTP/1.1");
client.println("Host: joeybabcock.me");
client.println(""); //mandatory blank line

For responses:

client.println("HTTP/1.1 200 OK");
client.println("Host: joeybabcock.me");
client.println("Content-Type: text/html");
client.println("Connection: close");
client.println("");
client.println("body data");
...

Again, any HTTP request/response must follow RFC 2161!
