I am doing some work on my site and I don't want any pages to be accessed
What can I put in the htaccess file to make the site unavailable for a day or so
I know I can do something with the index page but some people have
direct links and I don't want any part of the site to be accessed
This seems to be a pretty detailed tutorial on how to password protect a directory: http://www.ilovejackdaniels.com/apac...with-htaccess/
You might have a similar capability in your host's control panel, that will be easier to use.
Making the site unavailable could hurt your search engine rankings. Do it only if you're sure this is the way forward for your site.
