mod_rewrite

very power, very confusing tool.
http://httpd.apache.org/docs/2.0/misc/rewriteguide.html
http://httpd.apache.org/docs/2.0/mod/mod_rewrite.html
http://httpd.apache.org/docs/current/rewrite/remapping.html

enabling

was not enabled by default for my ubuntu 14.04 vm.

sudo a2enmod rewrite

redirect

Request: redirect all traffic from a domain, including any subpage, to the landing/index page of another domain
Condition: mod_rewrite is enabled. virtual hosts are used
Resolution:

 <VirtualHost *:80>
         RewriteEngine on
         RewriteCond %{REQUEST_URI} !^/index.html$
         RewriteRule .* http://newdomain.com/? [R=302,L]
         ServerName olddomain1.com
         ServerAlias olddomain2.com
         Redirect permanent / http://newdomain.com/
 </VirtualHost>
 
 <VirtualHost *:80>
         ServerName newdomain.com
         ServerAdmin [email protected]
         DocumentRoot /var/www/newdomain.com
         TransferLog /var/log/apache2/newdomain.com-access_log
         ErrorLog /var/log/apache2/newdomaincom-error_log
 </VirtualHost>
 

Disable SSLv2/3
Add the following to your apache config. I added mine right below the other SSL Entries specifying the engine, cert file and key file.

#Disable SSLv3
SSLProtocol All -SSLv2 -SSLv3

listen on non-standard port

On ubuntu 14.04, it is done by adding this:

~$ sudo vi /etc/apache2/ports.conf

Listen 80
Listen 8080
