Download via ASP. 1

[JohnCMolyneux]

Hi.

I've built a download for a website and I want to add logging of downloads. I want to do this via ASP so that a normal download link (with a URL ending in a filename) can be replaced with something like...

http://www.mysite.com/downloads.asp?id=15

...where id=15 refers to a filename stored in a database.

I can do everything I need, except the actual download.

For example, if I did the following...

http://www.mysite.com/downloads.asp?file=instructions.txt

...how do I make ASP return the file "instructions.txt"?

Thanks in advance,

John.

thinking at the keyboard (always a dangerous thing)

dim url
if request.querystring("file") <> "" then
url = "/downloadpath/" & request.querystring("file")
response.redirect(url)

should work I guess.

Thanks Chris - I'll give it a go.

Alternatively, you could actually store the file itself in a database, so that when you select fomr the database by the ID, you actually return the file, instead of just the location on the webserver. Research the BLOB field type and decide if it's something you might want to do.

Thanks disorder, but I've already discounted using the database, as I usually do with anything that's file based.

Actually, the suggestion that Chris gave is not actually what I'm looking for - I'm trying to not give the filename via the URL.

I'll have to look into attaching files to HTML and pass the filename back via that method instead.

If you just want to write a link to the page then this will do

if request.querystring("file") <> "" then
with response
.write "<a href='/filepath/"
.write request.querystring("file")
.write "'>Download "
.write request.querystring("file")
.write "</a>
end with
end if

Erm, no, thanks Chris. I'm going to look into attaching the file to HTML so as not to give a direct URL to anything.

You just have to use the Scripting.FileSystemObject to read the content of the binary file, then use Response.BinaryWrite to send it to the browser for downloading.

see thread entitled "binary stream issues" there's alot of discussion of how to get this to work for you

in the download page you would just do a ref# to file translation, through your db, then you could also up your request count, or log ip or whatever it is you're wanting to do at this point, then FSO to the file, and then stream it.
