);

Parameters

principal

The principal to use for the request; this must not be null.

scriptContext

The script context to use for the request; this must not be null.

globalObject

The object to use as the global for our request. Often, this is the outer Window, but it may also be a sandbox or backstage pass. This may be null, but if it is, the request cannot create a document. Prior to Firefox 23, this was always a Window.

baseURI

The base URI to use when resolving relative URIs when handling the request. This may be null.

loadGroup Optional

An optional load group used when performing the request. If this is specified, it is used even if the global has a window with a load group already established.
