Recently, somebody asked me, point blank
Chuck, how do I clear cache, anyway?When I tried to answer, I realised that I did not know - I just do it, following the menus by instinct. This strategy does not help me to advise the average blogger, posting in Blogger Help Forum: How Do I?, very effectively.
One of the challenges is that each browser - and different versions of each browser - have different menus and wizards, for every maintenance procedure, and for every different setting.
What we used to call "cache" and "cookies", so long ago, is now called "private data" - and there are multiple selections, varying by browser, for various components of "private data".
With Chrome, you clear private data using the Wrench Icon - Tools - "Clear browsing data" wizard. My selections for clearing are:
- Clear browsing history
- Clear download history
- Empty the cache
- Delete cookies and other site data
- Clear saved passwords
- Clear saved form data
With Firefox V3, you clear private data using the Tools - "Clear Recent History" wizard. My selections for clearing are:
- Browsing & Download History
- Active Logins
- Site Preferences
- Form & Search History
With Internet Explorer V8, you clear private data using the Tools - "Delete Browsing History" wizard. My selections for clearing are:
- Preserve Favourites website data
- Temporary Internet files
- Form data
- InPrivateFiltering data (this you may wish to read about)
With Opera V10, you clear private data using the Tools - "Delete Private Data" wizard. My selections for clearing are:
- Delete temporary cookies
- Delete entire cache
- Clear history of visited pages
- Clear history of downloads
- Clear bookmark visited time
- Delete all cookies
- Delete password protected pages and data
- Clear all email account passwords
- Clear Password Manager
- Delete persistent storage
- Close all tabs
With Safari V5, you clear private data using the Gear icon - "Reset Safari" wizard. My selections for clearing are:
- Clear history
- Empty the cache
- Clear the Downloads window
- Close all Safari windows
- Remove all cookies
- Remove all website icons
- Remove saved names and passwords
- Remove other AutoFill form text
- Reset all location warnings
Firefox appears to distinguish between "Cookies" and "Active Logins". If you examine the IE V8 "Delete Browsing History" screen, you'll note the advice about cookies.
Files stored on your computer by websites to save preferences such as login information.This makes it appear that the equivalent of "Active Logins" (aka "authenticated sessions", in some of my advice) may be simply part of "cookies", in Chrome and Internet Explorer.
Similar to clearing of "cache" is clearing of "cache, cookies, and active login sessions". You'll also want to know how to enable cookies and scripts.
Remember to restart the browser, after clearing any private data, or changing any settings. And note the possible effects, depending upon your Internet service, of cache outside your browser, which you cannot clear. And finally, consider how all of this fits into the topic of Layered Security - which includes filters in the browser, in add-ons in the browser, in applications on the computer, and in appliances on the network.
