send file from CGI

[detlef.reichl]

Hi,

in a webapplication, a user can select from some options. Depending on
the selection some files are packed together in a zip file and get send
to the user. So far it works perfect, but the zip file is not recognized
from the browser and it displays the data as garbage.

The code that sends the data:


print @cgi.header("type" => "application/zip")
print @cgi.header("length" => File.size(zipfile).to_s)

file = File.new(zipfile, "r" )
while true
begin
data = file.sysread(65536)
rescue EOFError
break
else
@cgi.print data
end
end



Any suggestions?

Cheers
detlef

Wouldn't be easier to redirect the clients browser to the zip file? In
addition is "application/zip" the correct mime type?

HTH,

why not? securing data this way is kinda stupid.

acording to http://www.iana.org/assignments/media-types/ it's.

but some shity browsers (read IE wants file to have .zip extension even
if it's something like bleh.html?file=bloh.zip)
