LARGE file upload components/controls/add-ons?

[darrel]

I briefly researched this a year or so ago for a project that never
materialized, but now I'm in the midst of one and need to look into this a
bit more.

I'm working on a site where the client want people to be able to upload
files up to 50mb in size via the web site. It's a contact form. Form
information is emailed, file is uploaded to server, and client can then
click on a link to go download the file that was uploaded.

Due to the size of these, I'm thinking a standard file upload control isn't
going to work and that I should invest in a more robust option that includes
the ability to 'tickle' the server to keep the connection open as well as
providing some sort of status/progress bar for the person uploading the
large file.

Any particular product anyone would recommend? It's a VB.net 1.1 web app,
btw.

We use the Telerik upload control (as well as their other controls) and it
does fine for files that size. It does *not* load the entire file into
server memory (like the standard FileUpload) and provides progress bars too.

Sounds like what I need.

In general, is it safe to say one should invest in this type of option for
anything over a couple megs in size?

It's difficult to generalize such a thing. If you are developing an intranet
app that will be run exclusively over a LAN, then you probably don't need a
progress bar for a 2MB file. On the other hand, if you expect users to be
connected over dial-up, then you'd probably want a progress bar for even the
smallest of file uploads.
