This interface provides a way to stream data to the web browser. This allows
loading of data from sources which can not be accessed using URIs and
nsIWebNavigation.
Prepare to load a stream of data. When this function returns successfully,
it must be paired by a call to closeStream.
@throw NS_ERROR_NOT_AVAILABLE
The requested content type is not supported.
@throw NS_ERROR_IN_PROGRESS
openStream was called twice without an intermediate closeStream.
| aBaseURI | The base URI of the data. Must not be null. Relative URIs will be resolved relative to this URI. |
| aContentType | ASCII string giving the content type of the data. If rendering content of this type is not supported, this method fails. This string may include a charset declaration, for example: text/html;charset=ISO-8859-1 |
Append data to this stream.
@note To append more than 4 GB of data, call this method multiple times.
| aData | The data to append |
| aLen | Length of the data to append. |
Notifies the browser that all the data has been appended. This may notify
the user that the browser is “done loading” in some form.
@throw NS_ERROR_UNEXPECTED
