The definition of 'session cookie' taken from Webopedia_
The main purpose of cookies is to identify users and possibly prepare customized Web pages for them. When you enter a Web site using cookies, you may be asked to fill out a form providing such information as your name and interests. This information is packaged into a cookie and sent to your Web browser which stores it for later use. The next time you go to the same Web site, your browser will send the cookie to the Web server. The server can use this information to present you with custom Web pages. So, for example, instead of seeing just a generic welcome page you might see a welcome page with your name on it.
If that doesn't make sense, don't worry. In short, what you need to know about cookies is that they help websites interact with your computer. When you log into a website like WebStarts, a cookie is saved to your computer through your web browser. Then, when you access another page on that website, it asks for the specific cookie for your session. If it is found, then you are able to access your account.
For this reason, you will have problems if your web browser does not accept cookies. Use the following steps to enable cookies and troubleshoot any problems you may be experiencing with WebStarts_
