Ignore cache when refreshing a web page Web Browsers
When developing a website, particularly editing images, I often have to clear browser cache to see the changes. This often involves opening preferences and finding the Empty Cache button on Firefox.

But much quicker way is to hold Shift when clicking reload in Firefox or Camino -- this will temporarily bypass the cache for that particular page. In Safari, use the Alt/Option key instead to get the same behavior.

[robg adds: While I've known about these keys for quite a while, I can't find them documented in Firefox, Camino, or Safari. I also thought they were documented here, but I had no luck searching.]

Ignore cache when refreshing a web page

In camino you can reset the cache by simply command+option+e, probably a similar one in firefox, i dunno

Ignore cache when refreshing a web page

I've found that Safarii's cache doesn't really speed up my browsing experience enough to make up for the pain of not refreshing properly, so I just lock the ~/Library/Caches/Safari folder to prevent caching. Works great. I haven't tested this on Camino or Firefox.

It's also Command-Option-E in Safari. In Netscape back in pre OS X days, Option-Reload used to do it (Super Reload). I believe that also works in Safari.

It is a shame that there's no settings for cache in Safari.

It's under the Safari menu. There are quite a lot of options there:

- About Safari
- Report Bugs to Apple
- Preferences
- Block Pop-up Windows
- Private Browsing
- Reset Safari
- Empty Cache

Ignore cache when refreshing a web page

It is documented in Gran Paradiso as a keyboard shortcut. This was how Netscape and IE behaved and probably Mosaic, the mother of all browsers.

I will attest that it was definitely there in Mosaic! It was of course needed even more in those days.

in my experience, this does NOT always work for Flash (SWF) files. They can be perniciously difficult to force-reload. However, i have found that it you load the swf file directly, and THEN do an alt/shift-reload, it generally ignores the cached swf file.

The shift-cmd-R shortcut is documented in Firefox under Help->KeyboardShortcuts->Navigation (section).

Also, for FF1.5 and above, you can use Clear Private Data to clear the cache instead of digging around through the preferences all the time. Should be mapped to the hotkey cmd+shift+del by default.

This is possible since Netscape Navigator 4, possibly even earlier...

not shift?
Authored by: rottiepaws on Feb 01, '07 11:14:22AM

hmm, so I have been wasting my time holding shift in Safari thinking it was doing something. I wonder why Safari is not shift?

because Apple is following convention. See the notes above regarding IE, Netscape and Mosaic.

The shortcut is documented in the support section of Camino's website, on the Keyboard Shortcuts page: http://www.caminobrowser.org/support/docs/shortcuts/

Camino has dynamic menus. Go to Menu > View > Reload Page. Now do it while holding down the shift key. Lots of other options too if you hold down various modifier keys.

Reloading a page twice in succession in Safari always clears the cache for me, except for Flash files as noted above.

I have found this will not work for modified frames, unfortunately. For frames, one has to open the offending frame in a separate window/tab, do the SHIFT Refresh, then go back to the framed top window. It would be nice if the browsers would force refresh the frames but they do not seem to handle frames correctly.

Then again, ask yourself, Am I on broadband? If the answer is Yes, kick yourself for keeping a cache in the first place. Problem solved.

I can just hope you meant this as a joke. Without any caching, the browser will load any and all images over and overe again - every little design element on ever single page. The webmaster will certainly appreciate this.
