TIL Clear-Site-Data

POSTED ON: Mar 17, 2023

Today I learned about the Clear-Site-Data header.

The Clear-Site-Data header clears browsing data (cookies, storage, cache) associated with the requesting website. It allows web developers to have more control over the data stored by a client browser for their origins.

// Single directive
Clear-Site-Data: "cache"

// Multiple directives (signing out of a website)
Clear-Site-Data: "cache", "cookies", "storage", "executionContexts"

// Wild card
Clear-Site-Data: "*"

Safari isn't fully supported yet. But it will!

Next: TIL the alternate keywordIf 'alternate' appears along with the stylesheet keyword, the linked file is an alternative stylesheet. It won’t be applied to the document, but it will be ready for when we need it.
Previous: TIL not obsessively trying to be DRYQuite often, DRY is applied to any duplication, rather than specifically to the duplication of business rules and knowledge. This is often made worse by automated code analysis tools, which will often highlight any duplication as a code smell.
