How would creating apache virtual hosts on the fly effect if any SEO

basically i can add directories:

/home/sites/domain1.com
/home/sites/domain2.com

etc

and it will work automatically www.domain1.com domain1.com, without adding an apache entry for each domain.

Code:

VirtualHost 206.4.112.13>

  UseCanonicalName Off

  ServerAlias www.*

  DocumentRoot /home/sites/

  VirtualDocumentRoot /home/sites/%2+



  <Directory "">

    Options ALL -Indexes

    AllowOverride ALL

  </Directory>



</VirtualHost>



<VirtualHost 206.4.112.13>

  UseCanonicalName Off

  ServerAlias *

  DocumentRoot /home/sites/

  VirtualDocumentRoot /home/sites/%0



  <Directory "">

    Options ALL -Indexes

    AllowOverride ALL

  </Directory>



</VirtualHost>

Question is will it have any effect vs each entry for each domain.
