Browser Cache: What, why and how.
If you have ever updated a CoalaWeb extension you may have noticed a post install message that looked something like this:
Please clear your Browser Cache and also take a look at the extension's various configuration options to see whats new and allow any updates to catch up.
If after reading the message mentioned above you have one of the following questions:
- What is browser cache?
- Why clear browser cache?
How do I clear browser cache?
Then this guide was written for you.
What is browser cache?
Any sophisticated website you visit is actually a composition of dozens, hundreds or even thousands of files. Even websites that are supremely optimized for speed are likely using a long list of files and resources that your browser is going to have to handle.
So how do Browsers do their part in speeding up the loading process?
Whenever you visit a website, your web browser saves certain information from that site to your computer’s hard drive in something called the “browser cache.” This is because your browser can then display the stored files from its cache much faster than it can pull fresh files from a website server. The next time you visit the same site, the use of locally stored cached files will help cut down page load time.
Cache is great so why delete it?
Each time CoalaWeb releases a new version of an extension it contains files and resources that have had changes made to them and in some cases files are added and or removed from the extension. These changes are made for the following reasons.
- Fix bugs and issues
- Add new features
- Update and improve code
- Remove obsolete code and files
If during the update process we change a file that your browser has cached, it’s going to keep serving the old, cached version of the file and you won’t see our most recent changes. This is why we ask you to clear your browser cache after updating a CoalaWeb extension.
Extra Information
A good first step whenever you encounter an issue on your website is to clear your browser cache. It won’t always fix the issue – but it is an important first diagnostic step to rule out before you assume that a more complicated issue is causing problems.
You’d be surprised how often what you think is a “huge” website bug is actually just a caching issue that goes away as soon as you clear your browser cache.
How do I clear my cache?
The process of clearing cache differs from browser to browser. Generally speaking, look for an option to delete cache or temporary files in your browser’s administrative settings.
