How to handle cookies in httpUrlConnection using cookieManager

I have a server request that returns multiple cookies, like that:

enter image description here

This is how I'm storing these cookies to the cookieManager:

HttpURLConnection connection = ... ;
static java.net.CookieManager msCookieManager = new java.net.CookieManager();
msCookieManager.put(COOKIES_URI, connection.getHeaderFields());


This is how I'm adding these cookies to the next connection:

connection.setRequestProperty("Cookie",
msCookieManager.getCookieStore().get(COOKIES_URI).toString());


Is it the right way to get the cookies from the cookieManager?,
I'm quite sure there is a better one...

Answer

Ok, the right way to do it is just like that:

Get Cookies from response header and load them into cookieManager:

static final String COOKIES_HEADER = "Set-Cookie";
HttpURLConnection connection = ... ;
static java.net.CookieManager msCookieManager = new java.net.CookieManager();

Map<String, List<String>> headerFields = connection.getHeaderFields();
List<String> cookiesHeader = headerFields.get(COOKIES_HEADER);

if (cookiesHeader != null) {
    for (String cookie : cookiesHeader) {
        msCookieManager.getCookieStore().add(null,HttpCookie.parse(cookie).get(0));
    }               
}

Get Cookies from cookieManager and load them into connection:

if (msCookieManager.getCookieStore().getCookies().size() > 0) {
    // While joining the Cookies, use ',' or ';' as needed. Most of the servers are using ';'
    connection.setRequestProperty("Cookie",
    TextUtils.join(";",  msCookieManager.getCookieStore().getCookies()));    
}
