Multi Apllication Server Setup

Question

Hi,
I have a big SAP BPC implementation (7 servers) that i need to implement at my client and the solution requires 3 Application servers. Do I need to install them differently? How will they communicate with each other? How will the Web server know which Application server to direct the requests to?
I went through the documentation and they say that i need to add another application server for every additional 70 concurrent users, but they don't say how to actually set it up. Any help or documentation will be appreciated.
Regards,

Hi,
It seems like the application server's IIS was not set to accept windows authentication,when we ticked it the landing page appeared.
In the web.config the last portion looks like this:
          <!-- base locations of servers -->
          <add key="AppServer_URL" value="http://server1/osoft/app"/>
          <add key="AppServer_AUTH" value="1"/>
Now my last question is, how do i add the last two application servers to the web.config file? Can i just add it like this?
          <!-- base locations of servers -->
          <add key="AppServer1_URL" value="http://server1/osoft/app"/>
          <add key="AppServer1_AUTH" value="1"/>
          <add key="AppServer2_URL" value="http://server2/osoft/app"/>
          <add key="AppServer2_AUTH" value="1"/>
          <add key="AppServer3_URL" value="http://server3/osoft/app"/>
          <add key="AppServer3_AUTH" value="1"/>
Obviously i will use IP addresses and not DNS names,but i just want to confirm my syntax.
Thank you very much for the assistance up to thus far.
