title: Where is an uploaded file prior to saving it when using the Asp.Net FileUpload control?
body: <p>I am trying to determine where Asp.Net and/or IIS store file uploads when you upload a file <b>BUT</b> before you call the <code>SaveAs()</code> method.</p>
  
  <p>I looked on <a href="http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.fileupload.aspx" rel="nofollow">MSDN</a> and I kind of get the idea that it's in memory and not put on the file system, but I can't find it anywhere it says this explicitely.</p>
  
  <p>I am trying to verify to IT that uploaded files (whose streams are passed on to FTP without ever calling <code>SaveAs()</code>) will not be automatically replicated by our server replication system.</p>
