All About Your Browser Cache

Problems with a library online research resource? These tips will help check if your Browser cache is the problem.  Did you try searching for title from Search Library Catalog + Articles?  If you are on-campus, try a different computer or a different web browser, such as switching from Chrome to Firefox. It sometimes helps to empty your web browser cache.

Off-campus?  If off-campus, did you remember to install/use the Pulse Secure Client connected to UC Davis Library VPN prior to visiting the publisher’s website?  If you forgot, be sure to clear your browser’s cache/cookies, then log-on to Pulse Secure and try accessing the resource again.  Many online research resources are only available to a recognized UCD IP address together with your UC Davis Computing Account (Kerberos).

  1. What is a browser cache? A web browser locally stores web sites on your computer’s hard drive which is called the “cache”.  The cache contains a history of all visited sites as well as images and  audio files.  Cookies are also stored in the cache.  They are often stored in the Temporary Internet Files folder.
  2. What is the purpose of browser cache? Upon revisiting a site, the browser will retrieve files from the cache instead of downloading the entire site again.
  3. What potential problems may arise with the cache? In many cases, the cached pages will not be current.  If you are having problems accessing an online research resource, it is advisable to clear the cache in order to ensure you are accessing the most current site and not accessing a stored prior search session. If the prior session was initiated off-campus without the use of the Pulse Secure VPN (see setup–desktop/notebooks and mobile), the cache can prevent recognizing you as an authorized user due to previously visiting  the website without proper credentials.  Be sure to clear the cache before you initiate the new session with the VPN.
  4. How can I resolve problems? Periodically clear the cache to ensure you are viewing the most current site and this will also improve the speed and performance of your browser.
