/**
|
|
* This class allows you to prefix an existing nsIAsyncInputStream
|
|
* with a preloaded block of data known at construction time by wrapping the
|
|
* two data sources into a new nsIAsyncInputStream. Readers of the new
|
|
* stream initially see the preloaded data and when that has been exhausted
|
|
* they automatically read from the wrapped stream.
|
|
*
|
|
* It is used by nsHttpConnection when it has over buffered while reading from
|
|
* the HTTP input socket and accidentally consumed data that belongs to
|
|
* a different protocol via the HTTP Upgrade mechanism. That over-buffered
|
|
* data is preloaded together with the input socket to form the new input socket
|
|
* given to the new protocol handler.
