How Do I Use Two Server To Host My Application Using Ip Addr

yes you are right ,for security reason we are doing this,my query is that is any thing extra we have to do to connect these server or just connecting these two server via DNS THEN USING conection string we can connect these two server ,its all we have to do??

I think, you wanted to connect to the DB server only for the data fetching from database. So connectionstring, which is placed in webconfig, is the way to get that. Is there any issue with connection? Isn't the connection string not connecting ?

i am using same connection string ,my problem is that will we need any thing in my web config that tells the web server to connect with DB server?
