ActiveSync via APM

Hi all,

I'm running into a similar error as Hamish -

May 1 20:43:06 ltm1 err apd[13484]: 01490000:3: AccessPolicyD.cpp func: "process_request()" line: 699 Msg: EXCEPTION AccessPolicyD.cpp line:619 function: process_request - error reading from socket
May 1 20:43:06 ltm1 err apd[13484]: 01490000:3: HTTPParser.cpp func: "parseHttpRequestHeader()" line: 174 Msg: Unknown HTTP method: OPTIONS

in my 11.1 HF1 config with APM in front of ActiveSync. It seems limited and sporadic and I haven't been able to tie it to a specific test case. I'm not using the _sys_APM_activesync rule itself, but a very slimmed down custom variant of it:

when HTTP_REQUEST {
  if { ![HTTP::cookie exists "MRHSession"] } {
     HTTP::header replace "clientless-mode" 1
     if { [HTTP::header Authorization] eq "" }{
        HTTP::respond 401 WWW-Authenticate Basic
     }
  }
}

I don't see anything in the _sys_APM_activesync rule that specifically addresses the HTTP method, but it's also not the same exact error message that Hamish was seeing. The "error reading from socket" concerns me. I have a max user APM license. Any suggestions?

Thanks,

Jen
