Clearing the cache and cookies in a browser

Cache and cookies

Your browser, in standard mode, saves a lot of information when you browse the web thanks to the "cache" and "cookies", in particular to save bandwidth, as the page no longer needs to be reloaded in its entirety on each visit.

This information can be useful to improve your user experience (not having to re-enter your identifiers, keep your site preferences, etc.), but it can also interfere with your access to some websites.

When you encounter problems logging in or browsing on a database or publication, you should try again after clearing these elements in your browsing history.

What types of access problems may clearing the cache and cookies solve?

  • you do not see the latest version of a site, or you continue to encounter a problem already solved: your browser has stored an obsolete page of the site in its memory
  • you log in, but you arrive on a blank page: your browser has stored too many cookie (collected trying to access a site), the site provider refuses to display the page
  • your browser offers you targeted advertising, recorded login data, or personal data you do not want to see appearing: your data is collected during your browsing, and is reused each time you browse the web.

In a nutshell : Ctrl+ F5
