Cookie Problem

Hi Everyone,
I need some help in Cookie. I have created a servlet, where i need to create a cookie which will hold value some of user id which is given in a login page. Code of the login page is not available, only url is known. Along this url a return url is added. After successful validation servlet will redirect to that return url. This login page is invoked from my servlet only.

Can any one suggest a way, by which I can capture the required information in side a Cookie.

N.B: I have tried Cookie[] cookie=request.getCookies(); and it's not working.

Is anything other than your Serlvet accessing this Cookie? What initially created the Cookie?

If you are looking at a pure-servlet solution, look instead at HttpServletRequest.getSession(boolean). This is a higher-level way to create session-persistent data in servlets. The getCookies() method is more low-level, and returns any Cookie data specifically sent from the browser (say if you created a Cookie using JavaScript).

Hi,
If you want to store your value in client browser then use cookie.
That should work , the work flow is for the first request the client will not have the value in cookie but after that you will have that value in cookie .

Hi Pete, Miku

Thanks for your suggestions. Few days ago I just came to know that value of the cookies were encrypted and the original value can be retrieved after following some formalities.
