Wikipedia:Bypass your cache

To speed things up and conserve communications bandwidth, browsers attempt to keep local copies of pages, images, and other content you've visited, so that it need not be downloaded again later. Occasionally this caching scheme goes awry (e.g. the browser insists on showing out-of-date content) making it necessary to bypass the cache, thus forcing your browser to re-download a web page's complete, up-to-date content. This is sometimes referred to as a "hard refresh", "cache refresh", or "uncached reload". The rest of your cache is not affected.

When you encounter strange behavior, first try bypassing your cache. In most cases you can use the simple instructions shown to the right, or see the complete browser-specific instructions below. If this is not enough, you can try performing a "purge" of Wikipedia's server cache (see instructions below). If problems persist, report them at Wikipedia:Village pump (technical).

If you are editing templates you may need to wait a few minutes before bypassing your browser cache in order to see the change in a page with the transcluded template.

In unusual circumstances, it may be worth clearing the entire cache (of your local browser).

These instructions work for Firefox, SeaMonkey, and other related browsers.

Unlike other browsers, Konqueror seems to bypass its cache whenever you reload a page.

If you would like to keep the data in your cache but test Wikipedia without using it, you can use the "incognito" browsing option.

Note: This method only works if the developer console remains open. Browser extensions are available for download that force the cache to be disabled at all times.

Click the ellipsis in the upper right-hand corner. Navigate to "Settings", "Clear browsing data" and then "Choose what to clear". Tick only the box: "Cached data and files"

To completely clear the cache in Internet Explorer 9 and later versions:

If you would like to keep your data in your cache and test Wikipedia with an empty cache, you can use Private Browsing mode.

Note: On a Mac the "Tools" menu does not have a "Preferences" option. "Opera → Preferences" is the correct menu item.

The Wikimedia servers cache a version of articles. When improperly displayed content is contained in a template or other transcluded page, bypassing your own cache might not be enough. You may need to purge the server cache of old page versions.

The server can be instructed to refresh its cache of a page's contents with the action=purge web address parameter. Add this to the end of the address. For example, to purge this page, visit one of the following:
