title: WebRequest.KeepAlive property doesn't exist in .net 2.0
body: <p>I am trying to set the KeepAlive property to true, however it doesn't exist.</p>
  
  <p>If I try to set it by adding it in header, I get the following error: This header must be modified using the appropriate property.</p>
  
  <p>Is there any method to set the KeepAlive property to true? Changing the framework isn't an option.</p>
  
  <p>Thank you.</p>
