Hi all,
I made a small and simple HTTP Server using Indy.
I would like to send a file to the client (eg. test.zip).
Browser ask to receive the file using a sort of dynamic page called
sendfile.html with parameter.
In other words the url requested from the client is that:
http://localhost/sendfile.html?name=test.zip
The problem I have is that:
If I click over the link in a page using the client (Internet Explorer), the
zip file is written on the html page.
If I right-click on the link and I choose "Save target as..." the zip is
correctly saved where I want, but the name is sendfile.html.
I use this row of code in the OnCommandGet:
HTTP->ServeFile(AThread, AResponseInfo, "c:\\test.zip");
but I tried also sending the file using ContentStream properties and the
result is the same.

In two words, when I click on a link to request a file, it's displayed over
the browser (instead of saved on disk) and if I right-click on the link, the
file is saved but with a wrong filename.

What I'm do wrong?
What's the right procedure to send a file requested with a sort of dynamic
page?

I hope I was sharp enough.

Thanks very much

Lapo

You are not specifying the proper header values to let the browser know that
the file is downloadable, and what its filename should be.

Add the following line of code before calling ServeFile():

    AResponseInfo.CustomHeaders.Values['Content-Disposition'] :=
'attachment; filename="test.zip"';
