In ASP.NET Core, a cache can be made in a Razor template as follows:

<cache expires-after="@TimeSpan.FromSeconds(3600)">
</cache>

I want to be able to clear all caches programmatically, is this possible?

My issue is I am creating the cache for a website and when a user changes content I want to clear all caches as what needs to show on the front end may change. Is this possible?

It's definitely possible. Unsure if you are using "default" Umbraco caching setup or what you've already tried, but I think you can find some guidance here if so: https://our.umbraco.com/documentation/Reference/Cache/ ?

I came across this blog https://carole.dev/blog/using-asp-net-cache-tag-helper-in-umbraco-9/. It shows how we can add the vary-by parameter to expire cache.

<cache expires-after="@TimeSpan.FromSeconds(3600)" vary-by="@siteNode.Id   @settings.UpdateDate">
</cache>

We can test this by updating some content and publishing in Umbraco. Now it will be updated in the cached page as the updated date “vary-by” value has changed, so the cache knows it’s no longer valid.
