* \file
|
|
* A response class that delivers an asset (file on disk).
|
|
*
|
|
* In future this will use a asset class, get from an asset class
|
|
* hash. The asset hash will be a shared resource between all
|
|
* workers.
|
|
*
|
|
* The asset class holds an open file descriptor wich is memory
|
|
* mapped and is able to give the correct pointer to neede data.
|
|
*
|
|
* This change will envolve changes in other parts of the response
|
|
* write system, as we no longer need to destinguish between piped
|
|
* and bufferd resources...we will allways work with a memory address
|
|
* only one time its allocated and one time a memory mapped file.
