Description

This issue was reported by Wim Heirman on the mod_python list:

When req.sendfile(filename) is called where filename is a symbolic link, only part of the file is sent to the client (as many bytes as there are characters in the symlink's file reference, so for a symlink pointing to '../index.html' returns the first 13 bytes of the correct file).

Wim suggested changing APR_READ to APR_FINFO_NORM in the apr_stat call in req_sendfile().
