  <p>The problem does not occur when executing an update trough the command line svn or the windows tortoise svn client.
  The server accesses the Internet trough a proxy, which is configured in tortoise svn's network settings. 
  Is there a way to tell cruisecontrol to use that same proxy?</p>
  
  <p>Any thoughts?</p>
