Your browser must accept "Cookies". Are Cookies Dangerous to My Computer? NO. A cookie is a simple piece of text. It is not a program, or a plug-in. It cannot be used as a virus, and it cannot access your hard drive. Your browser (not a programmer) can save cookie values to your hard disk if it needs to, but that is the limit of the effect on your system.

Other possibilities: Sometimes, simply exiting and restarting your browser will clear this error.

1. Your Web for Students session was left inactive for too long.
Be sure to log out of Web for Students. Leaving a Web for Students session logged in and unattended invites others to view and possibly change your student information.

2. You've already exited from Web for Students.
Once you exit, you must login again.

3. Your PC is running Web accelerator or download accelerator software.
If you have purchased or downloaded one of these accelerator programs, please uninstall or disable it.

4. You are using America Online's browser.
You can use Internet Explorer or Netscape with AOL. There is an issue with the AOL caching proxy server and the AOL Web browser. The workaround is to open a separate instance of IE or Netscape in order to access Web for Students. You most likely will run into problems if you use AOL's browser. The phone number for AOL technical support is (800) 827-3338.

5. Excessive system load.
The mainframe system could not respond to your request within a reasonable period of time.

6. You pressed your browser's Stop button or the Esc key, then clicked a link.
Interrupting Web for Students while it is working on your request requires that you log back in.

7. Your Internet provider uses HTTP proxies.
As a security measure, Web for Students builds a key to identify you and your session. This key includes your IP address. If you are coming through a proxy server, the proxy server may use multiple IP addresses. If the proxy attempts to get pages using different IP addresses, Web for Students will view this as a security violation and tell you that you must log in again.

Using Internet Explorer or Netscape Navigator, it is possible to use a proxy server but set exceptions. IE or Netscape will not go through the proxy for these sites listed as exceptions, thus alleviating the problem.

8. You are using WebTV. WebTV uses HTTP proxies (see above) with their set-top boxes.
There is currently no solution available for WebTV users. The problem lies with the configuration of the WebTV set-top boxes and cannot be resolved at OSU.

9. You double-clicked a link.
Links should be clicked only once.
