Caching

[jairogar...@gmail.com]

Hi, I have a problem.

Every time I make changes in the css or html not apply because the cache.

How I can prevent?

I've tried this, among other things:

         <Meta http-equiv = "Expires" content = "0">

         <Meta http-equiv = "Last-Modified" content = "0">

         <Meta http-equiv = "Cache-Control" content = "no-cache, mustrevalidate">

         <Meta http-equiv = "Pragma" content = "no-cache">

but it has not worked.

I hope you can help me.

Thank you.

J.

The easiest way is in the DevTools network panel. Check the box that disables the cache.

Worth noting, since you were unaware of this feature before, `disable cache` only applies when you have enabled the feature and the dev console is open, no need to toggle the feature on and off for normal browsing. ;)

First of all, thank you for the answer.

To me it's ok that solution, but, and the web user to navigate every day? How I make no common user suffers this problem?

Thank to all,

J.

Ahh, that is a slightly different question. Generally that is achieved one of several ways.

• Proper cache headers from your server
• cache busting URLS ie: <link rel="import" href="/path/to/my/cachedfile?updated=[timestamp or datestring]">
• directory versioning (similar to cache busting URL but the file path changes): <link rel="import" href="/v1/path/to/my/cachedfile">
• renaming -- the more drastic of the above options: <link rel="import" href="/path/to/my/file_previouslynamed_cachedfile">
