How to redirect to specific page if not logged in with .htaccess

Question

I am running apache2 and php5 in my windows PC.

I have protected my directory using .htaccess and.htpasswd. If login information is not set

Answer 1

I got this to work with an approach similar to AJ's. My .htaccess file is very similar to the following:

AuthUserFile /opt/www/htaccess
AuthType Basic

DirectoryIndex public.txt


    require valid-user
    FileETag None
    Header unset ETag
    Header set Cache-Control "max-age=0, no-cache, no-store, must-revalidate"
    Header set Pragma "no-cache"
    Header set Expires "Wed, 11 Jan 1984 05:00:00 GMT"



    FileETag None
    Header unset ETag
    Header set Cache-Control "max-age=0, no-cache, no-store, must-revalidate"
    Header set Pragma "no-cache"
    Header set Expires "Wed, 11 Jan 1984 05:00:00 GMT"


RewriteEngine On
RewriteBase /

RewriteCond %{HTTP:Authorization} !=""
RewriteRule ^$ secret.txt [L]

With this, the site behaves as follows:

1) Access the base URL -> see content from public.txt. 2) Access /secret.txt -> prompted to authenticate, and shown the contents of secret.txt. 3) Access the base URL again -> see content from secret.txt.

Using [L,R] instead of [L] will use a 302 response to handle the redirection. This is a good option if you want the redirection to be visible in the browser's location field.

Yes, I realize that this is a very late answer. The question was high in the Google search results, though, so I wanted to detail my approach in case I find myself doing the same search in the future. If anyone else benefits, it's even better.
