 This can now be used in other modules that need to install applications. All you would need to do is to have a require (as used with puppet-dotnet, by Liam Bennett) e.g.
 
     download_file { "Download dotnet 4.0" :
-        url                   => 'http://download.microsoft.com/download/9/5/A/95A9616B-7A37-4AF6-BC36-D6EA96C8DAAE/dotNetFx40_Full_x86_x64.exe',
-        destination_directory => 'c:\temp'
+      url                   => 'http://download.microsoft.com/download/9/5/A/95A9616B-7A37-4AF6-BC36-D6EA96C8DAAE/dotNetFx40_Full_x86_x64.exe',
+      destination_directory => 'c:\temp'
+    }
+
+    exec { 'install-dotnet-4':
+      command   => "c:\\temp\\dotNetFx40_Full_x86_x64.exe /q /norestart",
+      provider  => powershell,
+      logoutput => true,
+      unless    => "if ((Get-Item -LiteralPath \'${dotnet::params::f_reg_key}\' -ErrorAction SilentlyContinue).GetValue(\'DisplayVersion\')) { exit 0 }",
+      require   => Download_file['Download dotnet 4.0']
+    }
+    
+You can use this module and specify a proxy to download the file. It's usage would then be as follows:
+
+    download_file { "Download dotnet 4.0" :
+      url                   => 'http://download.microsoft.com/download/9/5/A/95A9616B-7A37-4AF6-BC36-D6EA96C8DAAE/dotNetFx40_Full_x86_x64.exe',
+      destination_directory => 'c:\temp',
+      proxyAddress          => 'http://myproxy.com:port',
     }
 
     exec { 'install-dotnet-4':
-             command   => "c:\\temp\\dotNetFx40_Full_x86_x64.exe /q /norestart",
-             provider  => powershell,
-             logoutput => true,
-             unless    => "if ((Get-Item -LiteralPath \'${dotnet::params::f_reg_key}\' -ErrorAction SilentlyContinue).GetValue(\'DisplayVersion\')) { exit 0 }",
-             require   => Download_file['Download dotnet 4.0']
+      command   => "c:\\temp\\dotNetFx40_Full_x86_x64.exe /q /norestart",
+      provider  => powershell,
+      logoutput => true,
+      unless    => "if ((Get-Item -LiteralPath \'${dotnet::params::f_reg_key}\' -ErrorAction SilentlyContinue).GetValue(\'DisplayVersion\')) { exit 0 }",
+      require   => Download_file['Download dotnet 4.0']
     }
+
+The proxy will be used as part of the download using PowerShell. This does not set a system wide proxy
