session-cookies

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center . Closed 6 years ago . I am developing a new website that needs the ability to detect if the user has visited the website previously, then direct them to a specific URL (i.e. example.com/welcomeback.html) if they have. I assume that this needs to be done with the usage of cookies and javascript, but I can't find any tutorials on this

I have seen some social network sites, if you have a user account, and when you open the browser and type the url, you will be directly loged in without inputting the username and password even if you close the computer and restart the browser your can still be automatically loged in which is different form before which you need to log in with your log in details, I think this is not only include the session cookie like the following setcookie(session_name(), '', time()-2592000, '/'); but might be more complicated than it. suppose if I use php, can anybody tell me how to implement this

Question is easy and basic. I've been working with PHP sessions for years and I always managed user login/logout this way: Start session ( session_start() call). Login: Store a value in the session (i.e. $_SESSION["user_id"] = 34 ). Check user logged: Check session value (i.e. isset($_SESSION["user_id"]) ). Logout: destroy session ( session_destroy() call and unset($_SESSION["user_id"]) ). This scheme has worked for me with very easy applications, but now I'm working in a bigger application and this approach is a bit problematic. For instance, I'm not able to implement the "remember" checkbox

I have a simple little script which I am using to set a cookie: function setCookie(cname, cvalue, exdays) { var d = new Date(); d.setTime(d.getTime() + (exdays*24*60*60*1000)); var expires = "expires="+d.toUTCString(); document.cookie = cname + "=" + cvalue + "; " + expires; } The problem I have this cookie is only set on one page, not across the whole domain. How can I adjust this function so that the cookie remains across the whole domain? You can specifiy domain ;domain=.example.com as well as path ;path=/ ("/" set cookie in whole domain) document.cookie = cname + "=" + cvalue + "; " +

ALL, Here is my web config in a Asp.net MVC4 application. I found if I set cookieless false ,everything goes fine. but If I don't want use cookie . then the application can not work.when I debug the application, I found the controller can not receive any request from the view. I think It is because when in the cookie-less mode, Something would be appended to the url before . like http:/ /localhost:8119/(S(3cicpjpagvpunr5he5fnfrj1))/. <configuration> <configSections> <sectionGroup name="system.web.webPages.razor" type="System.Web.WebPages.Razor.Configuration.RazorWebSectionGroup, System.Web

I am co-developing a simple web app in Rails 3.0.9 and I have realized that there is a possible session_id tampering possible via malicious request. Mind the fact, that this is my first RoR application, so I could be totally wrong in my conceptions. Current application functionality requires sessions so I turned to ActiveRecordStore session storage, installed it and started testing in primitive workflows. I noticed that Rails framework creates cookie with the name _session_id and value of some random hash-like string (in DB SESSION table this string corresponds to session_id column). If that
