We have no idea how to solve your problem because we can't see it. Please post your code using code tags. The code tags make the code look

like this

when posting source code files. It makes it easier to read, and can be copied with a single mouse click. Also, if you don't do it, some of the character sequences in the code can be misinterpreted by the forum code as italics or funny emoticons.

Unless the sketch is too large, it's better if you post your code, rather than attach it. When it's attached, we have to download it, create a folder then open your code in our IDE. Or perhaps open it in WordPad, which isn't very good for looking at code. And afterwards, the folder remains unless we navigate to the "Temp" folder and manually remove it. It's much easier to just view the code in your post.

Many questions can be answered by reading the documentation which is provided with the IDE, available under the help tab, or online here.

There are many other things that programmers do to make their code understandable. Please do them, as a courtesy to the members who volunteer their time to help you here. One is to use a standard indentation to clearly show the code blocks. Never put more than one statement per line. Place any brackets by themselves on a separate line. Before posting the code, use Ctrl-T in the IDE to reformat the code in a standard format, which makes it easier for us to read. Another is to give things descriptive names. You can name numerical constants, pin numbers, variables and many other things in this way.

To do this, you need to respond with a redirect HTTP response.

Normally, you respond with a message that starts

200 OK HTTP/1.1

and then has some headers. To make a redirect happen, you respond with a message that has

303 See Other HTTP/1.1

and that has a header named Location. You should also have a content body, which the browser will display if it doesn’t feel like obeying your redirect.

303 See Other HTTP/1.1
Location: http://google.com
Content-Type: text/html

<html><body>Redirecting you to google!</body></html>

All of this is defines explicitly in RFC2616, which if you are doing this sort of stuff a lot you will become very, very familiar with as the years roll by.
