W3C references

Widget Access Request Policy

This specification defines the security model controlling network access from within a widget, as well as a method for widget authors to request that the user agent grant access to certain network resources or sets thereof.

Opera Presto offers support for the Widget Access Request Policy, as described in the following sections.

<access> element attributes

For your reference, the following attributes are hyperlinked to their place in the online W3C Widget Access Request Policy document.

Attribute	Description	Support
origin	An IRI attribute that defines the specifics of the access request that is made.	Yes
subdomains	A boolean attribute that indicates whether or not the host component part of the access request applies to subdomains (as defined in RFC1034) of a domain in the origin attribute. The default value when this attribute is absent is false, meaning that access to subdomains is not requested.	Yes

Example

<widget xmlns="http://www.w3.org/ns/widgets">
  <name>My Opera</name>
  <!--
  Declaring subdomains as true, allows access to my.opera.com
  as well as other services provided by opera.com
  -->
  <access origin="http://opera.com" subdomains="true">
</widget>
