irule redirect pool uri http or https

Your requirement seems like the example of SSL::disable wiki.

you can use this code:

when HTTP_REQUEST { 
    switch -glob -- [string tolower [HTTP::uri]] { 
        "/content*" { 
            pool unsecure_80
            set usessl 0
        } 
        default { 
            pool secure
            set usessl 1
        } 
    }
}

when SERVER_CONNECTED {
  if { $usessl == 0 } {
    SSL::disable
  }
}

Note : Code edited... default statement must be without quotes.
