RE: file transfer over outbound port 80?

["Nero, Nick" <Nick.Nero () disney com>]

I use web sharing on IIS.  You can share a folder and downloads can be
done as if they were from web page.  If you can browse, you can get to
it.  I suppose there is a way to upload but I haven't ever configured
that.

In Windows 2000/2003, rightclick on a folder and choose websharing.
Pick the website you want it to hang off of (must be a local IIS server)
and you whould be good to go.

If port 80 is open, but does not go over a proxy, just have your FTP
Server listen there and set it for passive mode.
If port 80 does use a proxy, check to see if you can proxy your FTP over
that too. Most organizations allow proxied FTP, just not direct.

Here's our issue:

We often have engineers on site at customer locations where we need to
drop off or pick up files from a public file server. Currently we are
using ftp for this purpose however ftp outbound is being blocked by more
and more of our customers and only port 80 is open. 

My question is really what is the best way to work around this problem?
Is there a web-based application out there that only does this simple
job over port 80?
I have never seen this addressed here but I know we're not the first
ones to run into this issue. 


Thanks all for any help.
