Hi Mike,

 

I just figure out the owa has different uri after client login to owa. The uri of owa before login is /cookieauth.dll?Getlogon... but after login it directs to /owa. Is it because the owa's uri variable that defined at irule is different so client always hit the "default" condition below?

 

default { This final section takes all traffic that has not otherwise been accounted for and sends it to the pool for Outlook Web App if { [HTTP::header exists "APM_session"] } { persist uie [HTTP::header "APM_session"] 7200 } else { persist source_addr } pool exchange_2010_owa_pool7 }} }

 

How do I modify the irule so that it can works correctly? Appreciate your help. Thanks.

 

"/owa*" { Outlook Web Access if { [HTTP::header exists "APM_session"] } { persist uie [HTTP::header "APM_session"] 7200 } else { persist cookie insert 0 } if { [HTTP::header exists "Accept-Encoding"] } { HTTP::header remove "Accept-Encoding"

 

} pool exchange_2010_owa_pool7 return }
