help needed uploading file via a form

My system:
Linux 2.6.18-92.el5
PHP 5.1.6 (cli) (built: Jun 12 2008 05:02:35)
libcurl 7.15.5

I am trying to upload a file through a form. The steps I follow are:

1) visit the login page to get the __VIEWSTATE variable <--ok
2) login <--ok
3) visit the upload page to get __VIEWSTATE <-- ok
4) upload the file <-- NOT OK!!!

Here is the form:

<form name="Form1" method="post" action="quote_upload.aspx" id="Form1"
enctype="multipart/form-data">
<input type="hidden" name="__VIEWSTATE" value="fickshurt" />
<input name="file_path" id="file_path" type="file" style="WIDTH:
392px; HEIGHT: 22px" size="46" />
<input type="submit" name="upload_quote" value="Upload"
id="upload_quote" />
</form>

I have read a hundred web pages, tried a hundred different things, and
all I get back is either 1) 403 Forbidden or 2) 500 Internal Server
Error.

Here is the current set of CURLOPTs I'm using (some of which are
currently commented out.

     curl_setopt($ch, CURLOPT_COOKIEFILE, $cookypath);
     //curl_setopt($ch, CURLOPT_COOKIEJAR, $cookypath);
     curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
     //curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
     //curl_setopt($ch, CURLOPT_REFERER, $upload_url);
     //curl_setopt($ch, CURLOPT_USERAGENT, $useragent);
     //curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 1);
     curl_setopt($ch, CURLOPT_HEADER, 1);
     curl_setopt($ch, CURLOPT_URL, $upload_url);
     curl_setopt($ch, CURLOPT_VERBOSE, 2);
     //curl_setopt($ch, CURLOPT_POST, 1);
     curl_setopt($ch, CURLOPT_POSTFIELDS, $postfields);
     //curl_setopt($ch, CURLOPT_UPLOAD, 1);
     //curl_setopt($ch, CURLOPT_INFILE, $fp);
     //curl_setopt($ch, CURLOPT_INFILESIZE, filesize($uploadfile));
     curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);

Can somebody outline a solution or prompt me for more information?
I've spent four days on this already.

Thanks,
TomT
