Hide url of downloadable document

[TerryDad2]

I have a HyperlinkColumn that I want to completely hide the url from the client in both the browser and the code. I've got to prevent users from randomally trying other urls from the same folder to try to get other documents.

I am picturing that the HyperlinkColumn would instead of going to a url, fire off a server side funciton that gets the file and starts the download without showing the location to the client.

Any other solutions would be entertained as well.

One way would be to use a JavaScript function, e.g.,

DataNavigateUrlField = "myfilename"
DataNavigateUrlFormatString="javascriptpenfile();"

and then in the javascript:

function openfile() {
'open up url/scr/file here in java
}

...just an idea.

Another possibility would be the old ASP trick of creating a download page (or display page) that accepts some form arguments (such as filename) and then opens the file and binary writes it to the output. This way the user only ever sees the page that is actually doing the work and your real file can be located in another directory, such as a directory not in the web folder hierarchy.

It sounds like Tarwn's solution is what I am looking for. I'll search the ASP pages to see how to implement it. I've not seen that trick before. Do you have any suggestions of where to see examples of this code?

Thanks for the help.
