It only works because it silently discards the https: and replaces
it with http: . Actually, it disregards what is in front of // 
completely, whatever it is.  Even:

  url    = "foobar://www.ntg.nl/watistex.html"

works just 'fine'.


Anyway, perhaps someone can answer me this? I tried the ffi/curl code,
and the network stuff works, but only when I comment out the write
callback:

  lcurl.curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, ffi.cast("callback",discard));

If I dont, I get an error message from ffi that is:

  unable to convert argument 3 from cdata<unsigned long long (*)(void*, unsigned long long, unsigned long long, void*)> to cdata<vararg>
  stack traceback:
	[C]: in function 'curl_easy_setopt'
	[ctxlua]:42: in function 'check_status'
	[ctxlua]:1: in main chunk


And I have no idea what that actually means or how to fix it?

Best wishes,
Taco
