Clear Browser Cache/Temporary Internet Files and Cookies

If you are having problems connecting or you receive errors working PeopleSoft web-based campus applications you should clear the cache/temporary internet files and cookies on your web browser. This is always a requirement after a system upgrade.


In order to speed up web browsing, browsers are designed to download web pages and store them on your computer in an area called the cache. When you visit the same page for a second time, the browser speeds up the display time by loading the pages locally from the cache instead of downloading everything again. This sometimes results in less than current versions of web pages being displayed, along with problems on registration and authentication pages. 

Websites also send small text files known as cookies to your web browser in order to store information about your connection to their server, authentication information, preferences, etc. Cookies are particularly useful when you want a website to auto-sign you into a web service, but like the cache, should be deleted after a system upgrade.
