I have a login jsp which posts to a servlet. The servlet takes the login info, uses MD5 to "encrypt" the cookie's value, adds the cookie and forwards to another jsp. The second jsp contains a method call to the servlet's authenticateUser method which iterates through the cookies and returns true if it finds the correctly "encrypted" value in the cookie. ... |
7. Cookies coderanch.comIf i use a cookie.. will it be different from the cookie that the container creates??? Because, as per my understanding.... the container cookie (say with jsessionId) must expires with the session. And the session Id will be different for each session. Whereas, my application needs to preserve some data even after the session expires. So is it always that they ... |

This code creates a cookie named 'param1', and map its value to whatever the value of the query parameter 'param1' is, and its expiry value is 1800 seconds. developers don't need to worry about the location, the cookie is by default stored on client-end, where the location is where your browser store your temporary internet files. Hope that helps. |
I have created a small application for setting and getting cookie.

hi dears I read somewhere: A zero value indicates that the cookies are temporary and will be destroyed once the client closes the browser. But for example in shopping project,user does not want to close the browser and he log out and login again,and I think with setMaxAge(0) the cookies for previous user exist too. |

I am reading on a book and it is talking about session and cookie.

39. Cookies coderanch.comRather than stressing about a solution, write something atht doesn't suck too badly and provide comments. Our point is that as long as you aren't too wild and carefree in your code, it is unlikely to be as bad as you believe. And comment the expected behaviour so someone can fix it if there is a problem afterwards. |

Unless I'm missing something... Your listener doesn't fire because clearing cookies doesn't send an event to the server (and nor should it). Think of it this way: Say I have multiple session cookies to multiple servers (say, a 1000 of them) and the browser persists those cookies even if the server tells it NOT to. Now suppose I close all browsers ... |

52. Cookies coderanch.comHi all, What is the point in having getCookies() in javax.servlet.http.Cookie. I think at any point of time, there will be only one Session associated with a Client. So there will be one Cookie associated with that particular Session. That cookie will have a single key-value pair. The key identifies the client. So why we have to getCookies(), iterate the array ... |

55. Cookies coderanch.comActually, no. Or else I'm missing something. One could point to the fact that methods like getPath() and getDomain() exist and therefore I'm wrong. But if one experimented with these methods, they'd see that these always return null for cookies read from the request. But the API doesn't say this or anything towards what an HTTP request might contain. |
