HTLoadFile_Async_Init
NOTES:
Since we are reading a local file, we record that fact in the
request structure. If this request happens to end up in the
FileWriter class, that class can avoid writing a temp file
and simply read this file directly.
It is the responsibility of FileWriter to make sure that this
filename is not marked for deletion as a temporary file.
It is the responsibility of the caller (loaddoc.c) to make sure
that this string gets freed.
The "openType" parameter is used to determine if we are opening a local
file, or handling a "cache" file. This was done to condense the dcache
code with this code, since there was considerable overlap in functionality.
