Hi, max!
Here's what I use in my Wiki script:
MIME: make object! [
Extension_MIME: load %"Extension MIME.txt"
Type?: func [File [file!]] [
select Extension_MIME Extension? File
]
Data: function [File [file!]] [Data] [
Data: read/binary File
print [
"Content-Type:" any [
Type? File
'application/octet-stream
]
newline
]
write-io system/ports/output Data length? Data
Data: none
quit
]
]
View_File: func [Folder [file!] File [file!]] [
File: any [
if exists? Wiki_Files/:Folder/:File [
Wiki_Files/:Folder/:File
]
if exists? Folder/:File [
Folder/:File
]
if exists? File [
File
]
Rebol/script/header/File
]
if not found? find Inline_Extensions extension? File [
print rejoin [
"Content-Disposition: attachment; "
{filename="} form last split-path File #"^""
]
]
MIME/Data File
]
The key part is this line:
write-io system/ports/output Data length? Data
And these lines:
print [
"Content-Type:" any [
Type? File
'application/octet-stream
]
newline
]
I hope that helps!
