CLEAR Cookies and Caches in Chrome

Not a delicious sweet treat (in this context at least)

A cookie is a temporary file stored on your computer that is used to track activity in your web browser. Cookies can be used for a variety of reasons, some good and some no so legitimate. Some examples of good cookies can include:

• Tracking logins to a website (think of the Remember Me box visible on many sign in screens)

• Recording a shopping session and the contents of your online shopping cart

• Settings and preferences for particular sites

• Recent searches

Cookies can sometimes get corrupted or are not cleared correctly by the website that generates them and as a result the browser can get confused. An example of a bad cookie is the password reset screen constantly appearing for the school systems even after the password has been reset. Edumate can often exhibit some strange behavior with bad cookies, normally related to the markbook or learning tasks screens.

The following instrucitons apply to Google Chrome, the supported browser at PLC Armidale

• Click on the three dots in the top right corner of the Chrome window

• Highlight More Tools... and click on Clear Browsing Data...

• Ensure the option Cookies and Other Site Data is selected and the time drop down is set to All Time. 

• (optional) Turn on Cached Files and Images as well.

• Click on Clear Data

• If you now try to reload your required page it should open as expected.

NOTE: You will be prompted to sign in to your PLC services again, this is expected behaviour as the file recording your sign in to school systems has just been removed during this process

A computer cache is a temporary location for storing data for faster retrieval. A browser cache stores files from regularly visited sites in a hidden location on the computer instead of downloading from the internet each time the files are required. These files can be text, pictures, scripts - any of the components used to build the websites you see on your computer screen.

Bad cache files can cause some unexpected behaviour in a web browser. Most often this is seen with Edumate not being able to open particular screens, the Markbook and Learning Tasks are the two most common sections that have issues.
