| 7 * This class allows you to prefix an existing nsIAsyncInputStream | |
| 8 * with a preloaded block of data known at construction time by wrapping the | |
| 9 * two data sources into a new nsIAsyncInputStream. Readers of the new | |
| 10 * stream initially see the preloaded data and when that has been exhausted | |
| 11 * they automatically read from the wrapped stream. | |
| 12 * | |
| 13 * It is used by nsHttpConnection when it has over buffered while reading from | |
| 14 * the HTTP input socket and accidentally consumed data that belongs to | |
| 15 * a different protocol via the HTTP Upgrade mechanism. That over-buffered | |
| 16 * data is preloaded together with the input socket to form the new input socket | |
| 17 * given to the new protocol handler. | |
