I mean to check server environment variables which is what REMOTE_USER is.
I just want to know if the variable is defined on the server then I could do
this:
RewriteEngine On
RewriteCond %{REMOTE_USER} -e
RewriteRule ^(.*)$ - [S=1]
RewriteRule ^.*$ http://domain/login.html [R]
Right now when REMOTE_USER is not defined this line gets executed:
RewriteRule ^(.*)$ - [S=1]
I want that line to be skipped if REMOTE_USER has not been defined as a
server environment variable.
You can see the values in phpinfo(); It is only defined if the user is
logged in.
Why would a nonexistent variable evaluate to true?

The -f and -d flags for RewriteCond are for checking the file system,
not environment variables, although they can use environment variables
if necessary. For example:
RewriteCond %{DOCUMENT_ROOT}/%{ENV:foo} -d
would check that the folder named by the environment variable "foo"
exists in the document root.
