One or more sources can be allowed for the
Content-Security-Policy: manifest-src <source>; Content-Security-Policy: manifest-src <source> <source>;
<source> can be one of the following:
- 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.
http://*.example.com: Matches all attempts to load from any subdomain of example.com using the
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
- A schema such as 'http:' or 'https:'. The colon is required, single quotes shouldn't be used. You can also specify data schemas (not recommended).
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:URIs to be used as a content source.
blob:URIs to be used as a content source.
filesystem:URIs to be used as a content source.
- Refers to the origin from which the protected document is being served, including the same URL scheme and port number. You must include the single quotes. Some browsers specifically exclude
filesystemfrom source directives. Sites needing to allow these content types can specify them using the Data attribute.
- Allows the use of inline resources, such as inline
<style>elements. You must include the single quotes.
- Allows the use of
eval()and similar methods for creating code from strings. You must include the single quotes.
- Refers to the empty set; that is, no URLs match. The single quotes are required.
- A whitelist for specific inline scripts using a cryptographic nonce (number used once). The server must generate a unique nonce value each time it transmits a policy. It is critical to provide an unguessable nonce, as bypassing a resource’s policy is otherwise trivial. See unsafe inline script for an example.
- A sha256, sha384 or sha512 of inline scripts or styles. When generating the hash, don't include the <script> or <style> tags and note that capitalization and whitespace matter, including leading or trailing whitespace. See unsafe inline script for an example.
strict-dynamicsource expression specifies that the trust explicitly given to a script present in the markup, by accompanying it with a nonce or a hash, shall be propagated to all the scripts loaded by that root script. At the same time, any whitelist or source expressions such as
'unsafe-inline'will be ignored. See script-src for an example.
