Souce.fromURLで

import scala.io.Source

object Main {
 def main(args : Array[String]) : Unit = {

   println(
     Source.fromURL("http://blog.kzfmix.com/","utf8")
       .getLines
       .mkString
          )
 }
}

proxyの指定は

import scala.io.Source

object Main {
 def main(args : Array[String]) : Unit = {

   System.setProperty("http.proxyHost","proxy.co.jp")
   System.setProperty("http.proxyPort","8080")

   println(
     Source.fromURL("http://blog.kzfmix.com/","utf8")
       .getLines
       .mkString
          )
 }
}
