Does anyone know how to stop Knockout HTML templates from being cached (for dev purposes)? I don't have this issue with any other files (CSS, PHTML, XML, JS), it only happens with HTML templates.
As an example I will add the word test to the checkout button in the minicart. The file already exists, the only change I'm making is to add the word test.
<!-- ko i18n: 'Go to Checkout TEST' --><!-- /ko -->
File: app/design/frontend/VENDOR/THEME/Magento_Checkout/web/template/minicart/content.html
These are the steps I usually have to take to display my changes:
- Clear Magento cache (
php bin/magento c:f) - Clear browser cache
- Refresh
No change.
- Clear browser cache again
- Refresh
The change is now visible. This time I got lucky, sometimes it requires more cache clears and other times I give up and delete the caches, var/view_preprocessed and pub/static/frontend.
My questions are:
What causes this?
Why does it only affect HTML files?
Is there a workaround?

From my experience, we should disable Browser Cache when developing. It's one of the way for preventing Browser Cache, not full answer to this quesion.
For example:
Chrome: Network tab > Disable cache
UPDATE:
-Cache on the server side: my team had the same problem with Vagrant box and Puppet. The Puppet Master had the Opcache on the server side. So, the content was cached(can be some days). So, we need to clean the Opcache server.
