constant FTPPASS = "password"
global sDownloadStart
on mouseUp
put "test.zip" into tFileName
put "ftp://" & FTPUSER & ":" & FTPPASS & "#" & FTPHOST & "/" & tFileName into pUrl
-- start the download process, telling Rev to call the "downloadComplete" handler when finished
Load URL pUrl with message "urlProgress"

end mouseUp
on urlProgress pURL, pStatus, pBytesDone, pBytesTotal
put pStatus into fld "pf1"
switch item 1 of pStatus
      case "loading"
set the thumbPosition of sb "Progressbar" to round((pBytesDone / pBytesTotal) * 100)
         put the round of (item 1 of pBytesDone / 1024)&& "KB Downloaded" into field "status"
         break
      case "cached"

set the itemDel to slash
put "binfile:" & specialfolderpath("documents") & "/test.zip" into myPath
//put "data.file" into tFileName
put url pUrl into url myPath
answer "Download completed" with ok
-- to save memory, now unload the URL from memory
-- this also means that if you want to run the test again, it does not just use a cached version

answer error "The file could not be downloaded." with "ok"
end if
         break
     
   end switch
end urlProgress

Answer 1

Your urlProgresshandler is called after the loading of the URL finishes. To get a different status, you have to call another message or call the message in a different way, e.g.
on mouseUp
//delete URL "binfile:" & specialfolderpath("documents") & "/data.file"
put "data.file" into tFileName
put "ftp://" & FTPUSER & ":" & FTPPASS & "#" & FTPHOST & "/" & tFileName into pUrl
-- start the download process, telling Rev to call the "downloadComplete" handler when finished
// the callback message has only 2 parameters: url and urlStatus
Load URL pUrl with message "downloadComplete"
send "urlProgress pUrl" to me in 200 millisecs
end mouseUp
on urlProgress pUrl //,pStatus, pMessage,pbytesR,pbytesT
put urlStatus(pUrl) into pStatus
if item 1 of pUrl is "loading" then
put item 2 of pStatus into pBytesR
put item 3 of pStatus into pbytesT
put item 1 of pStatus into pStatus
send "urlProgress pUrl" to me in 200 millisecs
end if
end urlProgress
on downloadComplete theUrl,theUrlStatus
if theUrlStatus is "cached" then
-- work out a file name for saving this file to the desktop
set the itemDel to slash
put "binfile:" & specialfolderpath("documents") & "/data.file" into myPath
put "data.file" into tFileName
put url theUrl into url myPath
answer "Download completed" with ok
-- to save memory, now unload the URL from memory
-- this also means that if you want to run the test again, it does not just use a cached version
unload pURL
end if
-- check if there was a problem with the download
if pStatus = "error" or pStatus = "timeout" then
put libUrlErrodData(theUrl) into myErr
answer error "The file could not be downloaded."&& myErr with "ok"
end if
end downloadComplete
Let me know if this works (it should). If not, I'll have another look.
