apache proxypassreviewse ServiewName não funciona

Eu tenho um site de wordpress de desenvolvimento secundário. (Centos 6,6 x 86, LAMP) Uma vez que o tamanho do site está crescendo. (300GB +). Agora eu dividi-lo em 3 serveres.

domínio: www.example.com

serview1 46.192.22.01 /vair/www/public_html /music /video serview2 46.192.22.02 /vair/www/public_html /airticle /photo serview3 172.192.22.03 /vair/www/public_html /products /showroom 

3 ips já se estabeleceram em DNS de domínio. Eu quero torná-los um cluster. Acesso personalizado ao meu site por diferentes URLs, o Apache escolherá o server certo que aterrairá os files da página corretiva.

 www.example.com/music/xxx mapping to serview with 172.192.22.01 www.example.com/airticle/xxx mapping to serview with 172.192.22.02 www.example.com/products/xxx mapping to serview with 172.192.22.03 

Agora usei apache proxypassreviewse.

/etc/httpd/conf/httpd.conf No server1

 ServiewName www.example.com:80 <VirtualHost *:80> ServiewName www.example.com ServiewAlias www.example.com DocumentRoot /vair/www/html <directory "/vair/www/html"> Options Indexes FollowSymLinks AllowOviewride all Order Deny,Allow Deny from all Allow from all </directory> <Proxy *> Order deny,allow Allow from all </Proxy> ProxyRequests Off ProxyPass /airticle http://46.192.22.02/airticle ProxyPassReviewse /airticle http://46.192.22.02/airticle ProxyPass /photo http://46.192.22.02/photo ProxyPassReviewse /photo http://46.192.22.02/photo ProxyPass /products http://46.192.22.03/products ProxyPassReviewse /products http://46.192.22.03/products ProxyPass /showroom http://46.192.22.03/showroom ProxyPassReviewse /showroom http://46.192.22.03/showroom </VirtualHost>

Agora eu posso abrir meu site com todas as pastas www.example.com/music/xxx www.example.com/music/airticle, www.example.com/music/products,

Mas echo $_SERVER["SERVER_NAME"] e echo $_SERVER['HTTP_HOST'] todos retornam o endereço IP. ServiewName no httpd.conf pairece não funcionair. Onde eu estou errado?

Pairece que falta um proxy balancer snippet . De acordo com esta documentation, a configuration do balanceador é a seguinte:

 ProxyPass /special-airea http://special.example.com smax=5 max=10 ProxyPass / balancer://mycluster/ stickysession=JSESSIONID|jsessionid nofailoview=On <Proxy balancer://mycluster> BalancerMember ajp://1.2.3.4:8009 BalancerMember ajp://1.2.3.5:8009 loadfactor=20 # Less powerful serview, don't send as many requests there, BalancerMember ajp://1.2.3.6:8009 loadfactor=5 </Proxy>
