Dualform Tips: Flush that Cache

Why Can’t I See Any Changes?

After updating a web page, one of the most frequent questions we get asked by clients is why they can’t see the updates.  9.9 times out of 10, this is simply due to their browser cache needing flushed.

The Browser Cache

Every browser has a folder in which temporary files that have been downloaded from a web site are stored for future use.  When visiting a web page, the browser checks this folder to see if a file is in the cache already, and if so, the visitor does not have to re-download the file(s), and the web page they are visiting will load faster.

The Simple Refresh

Refreshing a browser reloads the web page while still using the old files from the cache, which doesn’t really help us in this situation, since the user will still be seeing the old files.

Flush It!

So, the user needs to flush their browser cache in order to clean out the old files so that the new version can be downloaded, so that changes can be seen.

Instructions

Following are step-by-step guides on how to clear the browser cache and force a browser to download all the latest data from a website.  We’ve listed the steps for the latest versions of the most popular desktop and mobile web browsers.  The steps are slightly different for older browser versions, so feel free to contact us directly if you need help.
