The source that a bunch of directives can have multiple of.

If nothing gets added, becomes 'none'.

Variants

Host(&'a str)

Internet hosts by name or IP address, as well as an optional URL scheme and/or port number.

The site's address may include an optional leading wildcard (the asterisk character, ''), and you may use a wildcard (again, '') as the port number, indicating that all legal ports are valid for the source. Examples:

  • http://*.example.com: Matches all attempts to load from any subdomain of example.com using the http: URL scheme.
  • mail.example.com:443: Matches all attempts to access port 443 on mail.example.com.
  • https://store.example.com: Matches all attempts to access store.example.com using https:.
Scheme(&'a str)

A schema such as 'http' or 'https'.

The colon is automatically added to the end. You can also specify data schemas (not recommended).

  • data Allows data: URIs to be used as a content source. This is insecure; an attacker can also inject arbitrary data: URIs. Use this sparingly and definitely not for scripts.
  • mediastream Allows mediastream: URIs to be used as a content source.
  • blob Allows blob: URIs to be used as a content source.
  • filesystem Allows filesystem: URIs to be used as a content source.
Self_

Refers to the origin from which the protected document is being served, including the same URL scheme and port number.

Some browsers specifically exclude blob and filesystem from source directives. Sites needing to allow these content types can specify them using the Data attribute.

UnsafeEval

Allows the use of eval() and similar methods for creating code from strings.

UnsafeHashes

Allows to enable specific inline event handlers. If you only need to allow inline event handlers and not inline
