So I'm using cURL to log into a website here, and spoofing the user agent. I have two constants: one called IOS that is an iOS user agent, and one called CHROME that is a Chrome user agent. Here is the code to log in:

    public function signIn($username, $password)
        $url = ""; 
        $cookie = "cookie.txt"; 

        $postdata = "screenName=$username&kclq=$password&submitEvent=1&TCNK=authenticationEntryComponent&enterClicked=true&ajaxSupported=yes"; 

        $ch = curl_init(); 
        curl_setopt($ch, CURLOPT_URL, $url); 
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); 
        curl_setopt($ch, CURLOPT_USERAGENT, IOS); 
        curl_setopt($ch, CURLOPT_TIMEOUT, 200); 
        curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 0); 
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
        curl_setopt($ch, CURLOPT_COOKIE, 1);
        curl_setopt($ch, CURLOPT_COOKIESESSION, 1);
        curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie);
        curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie); 
        curl_setopt($ch, CURLOPT_REFERER, ""); 

        curl_setopt($ch, CURLOPT_POSTFIELDS, $postdata); 
        curl_setopt($ch, CURLOPT_POST, 1); 
        $result = curl_exec($ch); 


In subsequent requests, I would like to change the user agent from IOS to CHROME, and it doesn't seem to work (I change to CHROME and the website still serves up a mobile page). When I run this request:

curl -L -X POST -b "cookie.txt" --user-agent " . CHROME . "

It does not serve up a desktop site, but a mobile one. Is it possible to change the user agent while logged in?

    The server is detecting your visit based on cookie also. So at the first line inside the function signIn() either empty the cookie file, or delete it.

    For example:

    file_put_contents($cookie, "");

    or delete it, curl will create a new one:
