Q. How do I delete my browsers cache and cookies, and why?


What is a web cookie? 

It is good practice to periodically delete or empty your browsers cache and cookies. Clearing your browser’s cache and cookies means that website settings (like usernames and passwords) will be deleted and some sites might appear to be a little slower because all of the images have to be loaded again. However if your browser starts to run slowly or you are getting error messages you should probably clear both. 

What is a cache?

Every time you visit a website, files (images,code etc) get stored on your pc belonging to that website so that the next time you visit it loads faster. The cache stores a copy of visited pages and then using that copy to open when you re-visit that page. If the webpage is the same date as the previously stored copy, then the computer uses the one on your hard drive rather than re-downloading it from the internet. In other words, you visit the library website on a Monday, as long as we don't edit the page, when you visit on Tuesday it loads the webpage mainly from your laptop and does not download it again. As you can imagine this speeds things up, especially if you have poor wifi.

What is  a cookie?

Cookies are a kind of short term memory for the web.  They are stored in your browser and enable a site to 'remember' little bits of information between pages or visits. They are widely used to make the web experience more personal, which is generally seen as a positive thing. However some cookies collect data across many websites, creating 'behavioural profiles' of people. These profiles can then be used to decide what content or adverts to show you. This use of cookies for targeting in particular is what the law was designed to highlight. By requiring websites to inform and obtain consent from visitors it aims to give web users more control over their online privacy. (http://www.cookielaw.org/the-cookie-law/)

Sometimes your browser might be set to delete the cache and cookies on exit, but most people do not manually set this, so the cache needs to be manually emptied. The link attached gives instructions on how to do this.

Sometimes if there are errors with the library databases or the website, you will be asked to delete your cache/cookies.
