1. Content-type for Binary File

How would I transfer a file via HTTP using mic's URLMON?

Right now I can do this:

   if get_file({"library.esp?getlist","library.esp"}) then
      if get_file({"getform.esp?rrc_p-1.dot","rrc_p-1.dot"}) then end if
   end if

get_file takes a URL (which is also the filename) -or- a URL and filename
(like above) and saves the download result into the filename. For the
library.esp?getlist URL above, it works fine. But for the .DOT file (which
is a Microsoft Word template), it cuts out at about 28kb, even though the
file is about 400kb. I'm sure it's because I'm using "Content-type:
text/plain;," but I don't know what to use.

Is there a better way to retrieve a binary file via HTTP WITHOUT having
to use a third-party software (like LibCurl, etc.)?

Of course, on the server side, the library.esp and getform.esp items are
Euphoria programs that are supposed to serve up something over the HTTP
connection. Works fine for text/html... :)

Thanks!!!

Kat, I tried using *.* as Content-type, but that still only gave me
27K or so.

Here's the code on the server that is sending the file... Maybe this needs
to be modified... (typed in, not copied)...

fn = open("c:\\templates\\" & form2send,"rb")
if fn > 0 then
   puts(1,"Content-type: *.*;\n\n")
   part = gets(fn)
   while not atom(part) do
      puts(1,part)
      part = gets(fn)
   end while
end if

Now, I know there's a get_bytes(), but that didn't seem to work either. But maybe I wasn't using it properly. So, if anybody can help me out, thanks in advance! :)

     Content-Type for Word documents should be "application/msword". But you 
have bigger problems...

     The Euphoria interpreter does not output to stdout in binary. There is 
no built-in method to change this output format. You therefore have no way 
of sending your binary data correctly in standard Euphoria. You might, 
however, be able to use the Windows API's to change the settings, or just 
output the file, as kat suggested.
