Exchange 2010 ActiveSync error with the latest Exchange iApp template

Thanks for responding. I downloaded the irule from www.f5.com/solution-center/deployment-guides/files/exchange-persist.zip Here is the section from the irule for ActiveSync: when HTTP_REQUEST {

 Offline Address Book and Autodiscover do not require persistence.

switch -glob -- [string tolower [HTTP::path]] {

    "/microsoft-server-activesync" {
         ActiveSync.
        if { [HTTP::header exists "APM_session"] } {
            persist uie [HTTP::header "APM_session"] 7200
        } elseif { [HTTP::header exists "Authorization"] } {
            persist uie [HTTP::header "Authorization"] 7200
        } else {
            persist source_addr
        }
        pool outlook-activesync-https_pool
        COMPRESS::disable
        CACHE::disable
        return
    }

There is a section at the end of the irule that I am not sure of the purpose. It is listed below: when HTTP_RESPONSE { if { [string tolower [HTTP::header values "WWW-Authenticate"]] contains "negotiate"} { ONECONNECT::reuse disable ONECONNECT::detach disable this command disables NTLM conn pool for connections where OneConnect has been disabled NTLM::disable } this command rechunks encoded responses if {[HTTP::header exists "Transfer-Encoding"]} { HTTP::payload rechunk }
