How to make post request using php keeping session alive with curl

Question

I am using php to scrape WWW. Example.com which requires session to login .I have logged successfully using php curl. Please check this link Keeping session alive with curl and php.Now In the link it shows how to make second request using same session cookie.

My problem is when i scrape

define("COOKIE_FILE", "cookie.txt");  
    // Login the user  
    $ch = curl_init('http://api.example.com/login/joe/smith');  
    curl_setopt ($ch, CURLOPT_COOKIEJAR, COOKIE_FILE);   
    curl_setopt ($ch, CURLOPT_RETURNTRANSFER, true);  
    curl_setopt($ch, CURLOPT_HEADER, true);  
    echo curl_exec ($ch);

    // Read the session saved in the cookie file  
    echo "<br/><br/>";  
    $file = fopen("cookie.txt", 'r');
    echo fread($file, 100000000);     
    echo "<br/><br/>";

    // Get the users details
    $ch = curl_init('http://api.example.com/user');
    curl_setopt ($ch, CURLOPT_COOKIEJAR, COOKIE_FILE); 
    curl_setopt ($ch, CURLOPT_COOKIEFILE, COOKIE_FILE); 
    curl_setopt ($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_HEADER, true);
    echo curl_exec ($ch);

My code is

define("COOKIE_FILE", "cookie.txt");
    // Login the user
    $ch = curl_init('http://api.example.com/login/joe/smith');
    curl_setopt ($ch, CURLOPT_COOKIEJAR, COOKIE_FILE); 
    curl_setopt ($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_HEADER, true);
    echo curl_exec ($ch);

    // Read the session saved in the cookie file
    echo "<br/><br/>";
    $file = fopen("cookie.txt", 'r');
    echo fread($file, 100000000);   
    echo "<br/><br/>";

    // Get the users details
    $ch = curl_init('http://api.example.com/user');
    curl_setopt ($ch, CURLOPT_COOKIEJAR, COOKIE_FILE); 
    curl_setopt ($ch, CURLOPT_COOKIEFILE, COOKIE_FILE); 
    curl_setopt ($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_HEADER, true);
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, 'username=abc&password=xyz&domain=123');
    echo curl_exec ($ch);

The output is

# Netscape HTTP Cookie File # https://curl.haxx.se/docs/http-cookies.html # This file was generated by libcurl! Edit at your own risk. www.example.com  FALSE   /unifyv3    FALSE   0 JSESSIONID    5366C3DB90DE7187A66E0BD19F595309

Your session has expired

Click here to log in again






Redirecting to Login Page in secs.

Everything works Perfectly well when the second request is GET request. When it comes to POST request the website returns "Your Session is Expired Please Login Again".

How this problem can be solved?.I have tried several solutions and searched in google, Nothing works.Finally decided to post here. Thanks in advance.
