|
|
* (2) implement nsIInputStream::readSegments
|
|
* (3) implement nsISeekableStream::seek
|

|
|
* History here is that we need to support both streams that already have
|
|
* headers (e.g., Content-Type and Content-Length) information prepended to
|
|
* the stream (by plugins) as well as clients (composer, uploading
|
|
* application) that want to upload data streams without any knowledge of
|
|
* protocol specifications. For this reason, we have a special meaning
|
|
* for the aContentType parameter (see below).
|
|
*
|
|
* @param aStream
|
|
* The stream to be uploaded by this channel.
|
|
* @param aContentType
|
|
* If aContentType is empty, the protocol will assume that no
|
|
* content headers are to be added to the uploaded stream and that
|
|
* any required headers are already encoded in the stream. In the
|
|
* case of HTTP, if this parameter is non-empty, then its value will
|
|
* replace any existing Content-Type header on the HTTP request.
|
|
* In the case of FTP and FILE, this parameter is ignored.
|
|
* @param aContentLength
|
|
* A value of -1 indicates that the length of the stream should be
|
|
* determined by calling the stream's |available| method.
