title: Gatling proxy configuration
body: <p>This is a followup to <a href="https://stackoverflow.com/questions/18710276/very-simple-gatling-simulation-failing">this question</a>. I'm using the same configuration. However, I'm trying to use an internal website through a proxy server. I'm not sure if  the following the correct way to configure a proxy in the simulation.       </p>
  
  <pre><code> val httpConf = http.proxy("http://proxy.server.address", 8080)
  </code></pre>
  
  <p>Here is my modified code. </p>
  
  <pre><code>package foo 
  import io.gatling.core.Predef._
  import io.gatling.core.session.Expression
  import io.gatling.http.Predef._
  import io.gatling.jdbc.Predef._
  import io.gatling.http.Headers.Names._
  import io.gatling.http.Headers.Values._
  import scala.concurrent.duration._
  import bootstrap._
  import assertions._
  
  class SimpleSimulation extends Simulation { 
      val httpConf = http.proxy("http://proxy.server.address", 8080)
  
      val scn = scenario("My scenario")
      .exec(http("My Page")
      .get("http://10.128.3.232:9201/index.html")) 
  
   setUp(scn.inject(atOnce(50 user))).protocols(httpConf) 
  
  }
  </code></pre>
  
  <p>I've also modified <code>conf/gatling.conf</code> to include the proxy. I'm not sure what's the correct way to configure the proxy. </p>
  
  <pre><code>http {
          #baseUrls = ""                                                          # default value for the base HTTP URLs
          proxy {
                  host = "http://proxy.server.address"                                                               # proxy host (blank means no proxy)
                  port = 8080                                                             # HTTP port
                  securedPort = -1                                                # HTTPS port (-1 means no HTTPS proxy)
                  #username = ""                                                  # proxy username (blank means no credentials)
                  #password = ""                                                  # proxy password
          } 
  </code></pre>
  
  <p>I'm getting the following exception when I run the simulation. </p>
