content aware switching

Hi users,
  
  I have been using mod_backhand for load balancing.
Now I want to use content aware dispatching techique.
Suppose I have 3 servers-x,y,z.
The web content is not fully replicated on these
servers.
In fact I have divided whole web content to three
parts
each served by one server. 
 
 Now here there are two cases for dispatching.
1. If a server doesn't know the contents with other
servers.
   In this case Iam using the directive "removeSelf"
   so that the server which contains the data will
serve.
2. If a server knows the content what other servers
have.
   Here which directive will be useful to redirect
   the request to a particular server?
   what is the difference between HTTPRedirectToName
   and HTTPRedirectToIP?
   Can I use these directives for this purpose?
   Or any other alternative?
   Please reply me with where I should put these
directives and with syntax.
 
 thanks,
 ravikumar
