How to Clear Browser Cache : Systems Division Support

What is cache and why should I clear it?

Each time you access a file through your web browser (Firefox, Chrome, etc.), the browser saves (i.e. caches) data it so it doesn't have to keep retrieving the same files or images from the web site each time you click Back or Forward.

You should periodically clear your cache to allow your browser to function more efficiently. This is especially important when we update our browser-based Citywide systems in the SF Employee Portal. If you have not recently cleared your cache, you may experience performance issues, trouble logging into the SF Employee Portal, and/or may not see the enhancements from the PeopleSoft update.

The drawback to clearing your cache is that your saved usernames and passwords will be deleted, and you will be prompted to verify your identification through multi-factor authentication, even if you have opted to trust your device for 30 days.
