Redirect to pool to bypass SSL offloading for Exchange Hybrid setup - syntax issue(s)

This only becomes an issue for SSL Offload not SSL Bridging. We need to tell the F5 to use SSL on the backend between the F5 & cas servers for /ews/mrsproxy.svc. First create a pool that contains all the cas servers on port 443. Next modify the existing exchange https vip to include a server-ssl profile. Finally, modify the combined/pool selector rule as follows:

Code
when HTTP_REQUEST {
    SSL::disable serverside
    switch -glob -- [string tolower [HTTP::path]] {
        "/ews/mrsproxy.svc" {
             Exchange Web Services ==> use 443 cas server pool and enable server ssl for o365 mailbox moves.
            if { [HTTP::header exists "APM_session"] } {
                persist uie [HTTP::header "APM_session"] 7200
            } else {
                persist source_addr
            }
            pool /Common/Exch2010_ssl_pool
            SSL::enable serverside
        COMPRESS::disable
            CACHE::disable
            return
}

This iRule disables serverside SSL for all http requests, then selectively enables serverside SSL for requests to the URI: "/ews/mrsproxy.svc". It then selects the new ssl/443 pool created earlier.

Note: there will be some outage/impact for new connections between adding the serverside ssl profile & modifying the iRule to disable serverside ssl on all other connections.
