Password protect a folder in Apache using .htaccess

mkdir -p /home/secure/
htpasswd -c /home/secure/apasswords developer
chown apache:apache /home/secure/apasswords
chmod 0660 /home/secure/apasswords

then in your htaccess add these:

AuthType Basic
AuthName "Restricted Access"
AuthUserFile /home/secure/apasswords
Require user developer

Redirect entire site to another domain, excluding folder

A site i’ve built for a campaign needed to be redirected to another site as the campaign expired, but one folder in the domain needed still to be accessible. htaccess to the rescue:

RewriteEngine on
RewriteRule !^uploads($|/) http://example.com%{REQUEST_URI} [L,R=301]

This rule does match any URL path that does not begin with either /uploads or /uploads/ (leading / is missing in the pattern due to the path prefix removal when used in .htaccess files) and redirects the request to the corresponding path at example.com.
