SharePoint and Office Integration - Part 2?

After doing some investigation from question "SharePoint and Office Integration using different browsers?" Ok I have the persisted cookie and session I know that there's OWA but it's not full feature (user have some complex Word and Excel files). The ActiveX control are not the problem - Using Fiddler I can see the request go out and come back it's the 302 to my.policy I have the following iRule to try to send incoming requests from Office user agent

when HTTP_REQUEST {
  log local0. ".......[HTTP::header User-Agent]"

  if { [HTTP::header User-Agent] contains "Microsoft-WebDAV-MiniRedir" } {
  log local0. ".......Header does contain info *****************************"
    HTTP::header insert "clientless-mode" 1
  }
}

when ACCESS_SESSION_STARTED {
   log local0. "**** Access Session Started ............"
   log local0. "Checking for cookies .................."

   ACCESS::session data set session.custom.usesso 0
   ACCESS::session data set session.custom.useWindowsAuth 0
   set usesso [HTTP::cookie UseSso_ClientServices]

   log local0. ">>>> Cookie value  ...($usesso)"
   if { $usesso == 1 }{
   log local0. ">>>> Setting   ...($usesso)"

    HTTP::header insert "clientless-mode" 1
     ACCESS::session data set session.custom.usesso $usesso
   }

   set user_agent [ACCESS::session data get "session.user.agent"]
   log local0. ">>> User Agent = $user_agent"

   if { $user_agent contains "MS-WebServices" }{
     HTTP::header insert "clientless-mode" 1
     log local0. "^^^^^^^^^ MS Web Serivce"
     ACCESS::session data set session.custom.useWindowsAuth 1
   }

   if { $user_agent == "Microsoft Office Protocol Discovery" }{
    HTTP::header insert "clientless-mode" 1
     log local0. "^^^^^^^^^ Office Product"
     ACCESS::session data set session.custom.useWindowsAuth 1
   }
   if { $user_agent contains "Microsoft-WebDAV-MiniRedir" }{
     log local0. "^^^^^^^^ WebDav"
     ACCESS::session data set session.custom.useWindowsAuth 1
   }
   log local0. ">>>VAR UseSSO ... ($usesso)"
   log local0. ">>> UseWinAuth variable set ... [ACCESS::session data get session.custom.useWindowsAuth]"
}

But it still not working do I need to do the clientless-mode in the HTTP_REQUEST?
