Cannot insert cookie

Hi all,

I tried to do URI based pool selection on first request. Then sequence requests will be directed to the same pool even the URI doesn't match. I use simple codes like following, however, the cookie can't be inserted. We're using outdated 9.4.8... Would anyone please help?

Thanks and rgds

when HTTP_REQUEST {
      set myCheck 0
      if {[HTTP::cookie exists "X-DWSpool"]} {
        pool test1-pool
      } else {
      switch -glob [string tolower [HTTP::uri]] {
        "/test1/*"      { 
                          pool test1-pool
                          set myCheck 1
                        }
        "/test2/*"      {
                          pool test2-pool
                        }
        default         { 
                          pool default-pool 
                        }
