No. Unless I made a mistake while testing AND misunderstood the documentation, even with -FollowSymLinks set, apache will follow symlinks (see POC). You might want to read the last line in section "FollowSymlink" in http://httpd.apache.org/docs/2.2/mod/core.html#options I, for myself, made the same assumption about -FollowSymLink, but the specification states, that the symlink-check is not race-free. > On Fri, Jun 24, 2011 at 5:14 PM, halfdog <[email protected] > <mailto:[email protected]>> wrote: > > For those, who did not already know: > > Due to specification, apache follows symlinks even when > -FollowSymLinks is set, when the data is modified concurrently.
