plume/cross_origin_opener_policy

Cross-Origin Opener Policy (COOP)

This response header controls whether a top-level document shares a browsing context group with cross-origin documents that open it or that it opens. Required alongside Cross-Origin-Embedder-Policy to enable cross-origin isolation.

See the MDN docs.

Types

CrossOriginOpenerPolicy

</>

A Cross-Origin-Opener-Policy header value.

pub type CrossOriginOpenerPolicy {
  UnsafeNone
  SameOrigin
  SameOriginAllowPopups
  NoOpenerAllowPopups
}

Constructors

```
UnsafeNone
```
Allows the document to share a browsing context group with its opener. Browser default.
```
SameOrigin
```
Isolates the browsing context to same-origin documents. Plume default.
```
SameOriginAllowPopups
```
Like SameOrigin, but keeps references to popups that either don’t set the header or set it to UnsafeNone.
```
NoOpenerAllowPopups
```
Newly-opened cross-origin documents are loaded in a new browsing context group. Same-origin documents, and cross-origin documents not opened from this one, are unaffected.

Values
