# `Processing of a Resource from Untrusted Source Blocked`
error in component `$sce`

    Blocked loading resource from url not allowed by $sceDelegate policy.  URL: {0}

## Description

AngularJS' `Strict Contextual Escaping (SCE)` mode (enabled by default) has blocked loading a resource from an insecure URL.

Typically, this would occur if you're attempting to load an Angular template from an untrusted source. It's also possible that a custom directive threw this error for a similar reason.

Angular only loads templates from trusted URLs (by calling `$sce.getTrustedResourceUrl` on the template URL).

By default, only URLs that belong to the same origin are trusted. These are urls with the same domain and protocol as the application document.

The `ngInclude` directive and directives that specify a `templateUrl` require a trusted resource URL.

To load templates from other domains and/or protocols, either adjust the `whitelist`/ `blacklist` or wrap the URL with a call to `$sce.trustAsResourceUrl`.

Note: The browser's Same Origin Policy and Cross-Origin Resource Sharing (CORS) policy apply that may further restrict whether the template is successfully loaded. (e.g. neither cross-domain requests won't work on all browsers nor `file://` requests on some browsers)
