title: DownloadString Path error
body: <p>I'm using the <code>Invoke-Expression</code> cmdlet in PowerShell to load modules.</p>
  
  <p>The following code works as intended.</p>
  
  <pre><code>$url="http://pastebin.com/raw/FuxtpN69"
  
  IEX (New-Object System.Net.Webclient).DownloadString($url)
  </code></pre>
  
  <p>But when I try using variables to split the domain and the page.</p>
  
  <pre><code>$u="http://pastebin.com"
  $rl="/raw/FuxtpN69"
  
  $url="$u$rl"
  
  IEX (New-Object System.Net.Webclient).DownloadString($url)
  </code></pre>
  
  <p>I get the following path error:</p>
  
  <pre><code>Exception calling "DownloadString" with "1" argument(s): "The given path's format is not supported."
  At line:8 char:53
  + IEX (New-Object System.Net.Webclient).DownloadString &lt;&lt;&lt;&lt; ($url)
      + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
      + FullyQualifiedErrorId : DotNetMethodException
  </code></pre>
  
  <p>Can someone help me? Thanks in advance.</p>
