How to remove cache from my Block class?

Question

I need to remove the cache from my Block class, even if it removes the cache from the entire page.

How could I do it?

• Mattia Kozianowski: You've already tried to add cacheable=false in your layout xml? More info here: devdocs.magento.com/guides/v2.3/extension-dev-guide/cache/… Example: meetanshi.com/blog/…
• Rafael Corrêa Gomes: Yes @MattiaKozianowski, but in this case, I can't control it via admin.

Answer 1

You can implement the HTTP class and call the method setNoCacheHeaders, as you can see below.

use Magento\Framework\App\Response\Http;
public function myCustomMethod(){
 $this->response->setNoCacheHeaders();
 ...
}

It will implement this module below, which will set no-cache in the header.
