If anyone is interested here is the code that I have written so far https://docs.google.com/folder/d/0B5ghoqfnILgZd01HdlY3ZE1MVW8/edit .

It seems to trip up at the point where a request is made to the URL within the javascript returned after submitting the login form.

I don't understand how javascript would be involved when you're doing server side scripting.

timmmay: I don't understand how javascript would be involved when you're doing server side scripting.

Yes I think I am confused. Here is an example of what is returned after submitting the login form:

<html>
<head>
    <script type="text/javascript">
        function redirect()
        {
            window.location.replace("http://www.trademe.co.nz/Members/Login.aspx?url=%2fMyTradeMe%2fDefault.aspx&secure=&login_attempts=1&quick_register=&firstname=Liam&email=my_email%40gmail.com&auto_login=&captcha=&err=0&login_success=True&dbs_id=39A6D8A3-130E-4FFC-B725-08C23883208C&region_id=2&session=%7BE3135B5C-570F-4399-B264-10118DE1FE30%7D&shareOfVoice=1&api_confirm=&bid=4,1,3&adParams=g%3dM%26bd%3d627615648000000000%26sb%3d13");
        }
    </script>
</head>
<body onload="javascript:redirect();">
</body>
</html>

Javascript is usually UI stuff, unless they're doing something tricky. A login should be a simple form post, it'll return a cookie, capture that and send it in with any future requests you make so it knows you who you are.

Do you have much web development experience?

Yes I do have web dev experience. I dunno I can't see that html doing anything other than redirecting...

Is that's what's returned after you submit the login form manually, or with your software?

It looks like a simple redirect to me, telling your browser to open another URL.

It is returned in both cases. However when using the browser after requesting the URL in that script I am redirected to the "My Trademe" page. In the code I just get redirected back to the login page.

Did you use the firefox plugin I suggested to see if a cookie's being returned at the same time? I would bet it is, but I don't want to make it too easy for you ;) If you open that URL with your code you'll need to send the cookie as well.

This all guesswork, but I think it'll lead you in the right direction.

The JavaScript is attracted to clicking of login form, The redirection could be done through standard html client requests.
Workng on some php to display session cookies of the login process.
