Functions
HttpResponse	httpResponseAsset (const char *fname, size_t nfname, time_t exptime)

Detailed Description

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.
