vboxsf and small files
i am using a virtual machine (vbox) as a webserver and connect both via shared folders, so i do not need to set up smb/nfs/sshfs or anything else. that way i can work with my ide on the webserver, but do not have one installed on my laptop. but there seems to be a problem with small files (about 2KB), e.g. .css-files. the apache delivers after small changes a css file, but not the modifed one. it is an old version with the same length of the new, although the length is like the new one and the timestamp is also renewed. so if your new .css-file is smaller then the old one, it has a padding of zeros. there is a workaround to add EnableSendfile Off and EnableMMAP Off into the apache.conf.
