Have you tried using something like ssh+rsync or scp (ssh copy) from the source server (i.e., the process that generates the file could "export" it)? If you set up public key authentication then the script wouldn't need to worry about authentication (though you would need to make sure that the private key was properly secured).

How often is it updated? Every X seconds, minutes, ... hours? How often will users hit the application? It would seem wasteful to fetch it from the remote server every time if it isn't changing (I'm unfamiliar with LWP::Simple, but it doesn't seem to mention caching in the perldoc), especially if many users are hitting it often. At the same time, if it's changing too often, you might end up having issues trying to push it from the source server (among other things, synchronization issues). It might be over my head, but I'm just trying to push some ideas. :) > I've managed to do what I needed to do by forcing the end user to launch a > local script that copies the files across the network everytime they need to > access the page that uses the data.

Do you mean they go to a copy page and then go to the processing page (i.e., Flash application) or do you mean that the coping page becomes the Flash application page? Assuming you can't push the file from the source server, could you use an asynchronous request from Flash to the copy script on the destination server instead of having the users jump around? When the request returns successfully, you can then request the XML data? I'm just trying to get an idea of the whole picture. :) -- Brandon McCaig <bamcc...@gmail.com> V zrna gur orfg jvgu jung V fnl. Vg qbrfa'g nyjnlf fbhaq gung jnl.
