Redirect a subdomain on Elastic Beanstalk don't work

I test webapp on AWS Elastic Beanstalk (Tomcat 8).

I would like to rewrite third level domain requests to specific urls.

For example:
request aaa.example.com rewrite to example.com/#!aaa
request bbb.example.com rewrite to example.com/#!bbb
etc...

This is Elastic Beanstalk /etc/httpd/conf.d/elasticbeanstalk.conf

<VirtualHost *:80>
  <Proxy *>
    Order deny,allow
    Allow from all
  </Proxy>

  ProxyPass / http://localhost:8080/ retry=0
  ProxyPassReverse / http://localhost:8080/
  ProxyPreserveHost on

  RewriteEngine on

  RewriteCond %{HTTP_HOST} ^aaa.example.com [NC]
  RewriteCond %{HTTP_HOST} ^www.aaa.mydomain.com [NC]
  RewriteRule ^(.*)$ http://ift.tt/1WrMly3 [L]

  RewriteCond %{HTTP_HOST} ^bbb.example.com [NC]
  RewriteCond %{HTTP_HOST} ^www.bbb.example.com [NC]
  RewriteRule ^(.*)$ http://ift.tt/1MStbjg [L]

  RewriteCond %{HTTP_HOST} ^ccc.example.com [NC]
  RewriteCond %{HTTP_HOST} ^www.ccc.example.com [NC]
  RewriteRule ^(.*)$ http://ift.tt/1WrMn98 [L]

  ErrorLog /var/log/httpd/elasticbeanstalk-error_log

</VirtualHost>

But rewrite don't work.
Hope it's clear enough, can you point me in the right direction?
