SorryPage with iFiles on 11.3 HF8

There is no issue with CaSe , I have confirmed it by rewriting code and uploading files again with lower case names

since there is if-statement (HTTP::uri eq /sp) before switch, /logo and /background won't hit the switch-case (because it is not equal to /sp).

  if { [HTTP::uri] eq "/sp" } {
    switch [HTTP::uri] {
      "/sp" {
        HTTP::respond 200 content [ifile get "index"] "Content-Type" "text/html"
      }
      "/logo" {
        HTTP::respond 200 content [ifile get "logo"] "Content-Type" "image/png"
      }
      "/background" {
        HTTP::respond 200 content [ifile get "background"] "Content-Type" "image/jpeg"
      }
    }
  }
