Help with http

Hi all,
I need some help understanding how the second line works:

Code:

// Make a HTTP request:
    client.println("GET /search?q=arduino HTTP/1.0");
    client.println();

The complete program can be found at http://arduino.cc/en/Tutorial/WebClient

I have been looking up info about RFC2616 but it's not helping much.

I need simple examlpes of how I would use "GET" with it not being in a program. Would I use it in an html file or safari browser? Could I use "get" on a LAN setup and not the internet? At this point I'm not sure how to ask the question yet!

FYI, an Arduino is a SBC with an ethernet shield attached, that is programmed and able to control things.

Thanks for any help.
If this should be in another area of the forum let me know?

Once you establish a connection to a remote server, that server supports various commands.

If you open an HTTP session, the commands the server supports are limited to OPTIONS, GET, HEAD, POST, PUT, DELETE, TRACE, CONNECT, and PATCH.

So what you're doing here is:
1) Connect to server.

2) Ask the server "I would like to GET the file `search` in your web root, with the argument q equal to "arduino". Please use HTTP/1.0 in your response."

Thanks Dan for your reply.

Is it possible to GET a "file" from my LAN without actually running a server such as apache? I think that the answer is no but I'm not sure.

You need some kind of server to serve files. FTP, HTTP, SAMBA, SFTP, SSH, (etc etc unto ten generations).

You definitely absolutely need a web server to execute PHP files and return the output to you. If you just want to pull down the PHP source file without executing it, regular old file servers will work.
