| michael@0 | 7 | * This class allows you to prefix an existing nsIAsyncInputStream |
| michael@0 | 8 | * with a preloaded block of data known at construction time by wrapping the |
| michael@0 | 9 | * two data sources into a new nsIAsyncInputStream. Readers of the new |
| michael@0 | 10 | * stream initially see the preloaded data and when that has been exhausted |
| michael@0 | 11 | * they automatically read from the wrapped stream. |
| michael@0 | 12 | * |
| michael@0 | 13 | * It is used by nsHttpConnection when it has over buffered while reading from |
| michael@0 | 14 | * the HTTP input socket and accidentally consumed data that belongs to |
| michael@0 | 15 | * a different protocol via the HTTP Upgrade mechanism. That over-buffered |
| michael@0 | 16 | * data is preloaded together with the input socket to form the new input socket |
| michael@0 | 17 | * given to the new protocol handler. |
