How could i Post binary data to perl cgi?

[Alejandro Tejada]

Hi Developers,

I have been working hard to employ
the method "post" for uploading
files to a web server.

I have used "HTTP interceptor v1.3"
to check the differences between the
data send by browsers and RR/MC.

These are the results:

Http headers send from Netscape:

POST /cgi-bin/upload.cgi HTTP/1.0
Referer: http://www.mywebsite.com/postfiles.html
Connection: Close
User-Agent: Mozilla/4.8 [en] (Win98; U)
Host: www.mywebsite.com
Accept: image/gif, image/x-xbitmap, image/jpeg,
image/pjpeg, image/png, */*
Accept-Encoding: gzip
Accept-Language: en
Accept-Charset: iso-8859-1,*,utf-8
Content-type: multipart/form-data;
boundary=---------------------------277072699622422
Content-Length: 15909

Data found after header end:

-----------------------------277072699622422
Content-Disposition: form-data; name="FILE1";
filename="C:\Mis documentos\candado.gif"
Content-Type: image/gif

Based in these results, i changed the script
to closely match the http produced by Netscape:

This was the headers result:

POST /cgi-bin/upload.cgi HTTP/1.1
Host: www.mywebsite.com
User-Agent: Metacard (Win32)
Content-Length: 15703
Content-type: multipart/form-data

Data found after header end:

Content-Disposition: form-data; name="FILE1";
filename="C:\Mis documentos\candado.gif"
Content-Type: image/gif

GIF89aJ 

But the server returns
Malformed Post request. :-(

This is the script that
produced this malformed post:

on mouseUp
  -- Setting httpheaders as recommended by Dave Cragg
  -- in the message "HTTP headers for posting data"
  put "Content-type: multipart/form-data" into
tHeaders
  set the httpHeaders to tHeaders

put "http://www.mywebsite.com/cgi-bin/upload.cgi" into
tUrl
  put "Content-Disposition: form-data; name=" & quote
& "FILE1" & quote & "; filename=" & quote & "C:\Mis
documentos\candado.gif" & quote into tString
  put crlf after tString
  put "Content-Type: image/gif" after tString
  put crlf & crlf after tString
  
set the customprop1 of the topstack to url
"binfile:C:/Mis documentos/candado.gif"
put the customprop1 of the topstack after tString
  put crlf after tString
  post tString to url tUrl
  -- put tString -- uncomment for debug
  if the result is empty
  then
    put it --
    set the htmltext of fld "result" to it
else
    answer the result
  end if
end mouseUp

If you could see the errors in this script,
post them here or send clues to my mail.

Thanks in advance.
