I've been trying to get SSI to work for an entire virtual host. I have XBitHack Full and I left the .shtml directives alone. If I use
<Directory "/some/directory">
Options Includes
</Directory>
under the virtual host directives, I can get SSI in that directory. However, I want it for the entire host. I've already tried using the root directory and it doesn't work.
Oh...one more thing, after a few restarts (via the httpd script), apache refuses to start again. Rebooting the machine fixes it though.
