Download only part of a file with ReceiveHTTPMemory()?

[BarryG]

There's a large text file (1 MB) that I'm currently downloading with ReceiveHTTPMemory() but I really only need the first 1 KB of it. Downloading the entire 10 MB just to use Left() on the data is silly. The ReceiveHTTPMemory() command doesn't have a flag to stop downloading after X bytes, so how would I do that? Thanks.

ReceiveHTTPMemory() does not support header parameters, so use HTTPRequest() instead:

Code: Select all

NewMap header$()
header$("Range") = "bytes=0-1023"

request = HTTPRequest(#PB_HTTP_Get, "https://...", "", 0, header$())
If request
  response$ = HTTPInfo(request, #PB_HTTP_Response)
  Debug StringByteLength(response$, #PB_Ascii)
  FinishHTTP(request)
Else
  Debug "Error"
EndIf

However, you must ensure that the server supports HTTP requests with ranges.
