The DominoDisableUploadChecks isn't needed because the upload is performed in 2 steps: I first do an ?openForm request to the target form. That form contains a file upload control, so the response of the request gives me a valid name for the file data (%%file.xxx). I then use that name when uploading the file(s). Drop me an email and I'll send you the demo database. Hi,

I would be really interested in seeing that working - particularly interested why you do not need the DominoDisableUploadChecks. Are you performing the upload within the Notes database or from another domain? That sounds great Mark.

It doesn't use Flex, but a combination of HTML, Javascript, CSS and the "hidden" Flash component. The DominoDisableFileUploadChecks isn't required and it does a basic post to a NotesDocument without using a servlet. I'm currently working on an accompanying article describing what it does and it's features and will post it when done. Regarding the SSL question: although not tested it should work with SSL, but only with trusted certificates, not self-signed certificates. This is probably the same for a Flex based solution.

Need to get this working in the first place. But once I'm there I will certainly consider SSL as well. To be honest I haven’t given SSL yet much attention.

Great explanation. In many ways development for Domino and Lotus Notes even with XPages is quite far behind compared to other environments, but at the same time it has many advantages.

I'm using the method described here... http://flexdomino.blogspot.com/2010/07/how-to-session-authenticate-flash.html to authenticate a Flex/Flash session with a Domino server and it seems to be working fine with all browsers. Having said this I have not been experimenting with file uploads via HTTP post. So I'm not sure if this authentication method will help you. An alternative to an HTTP post could be web services. Unfortunately a file upload via a Domino web service causes the HTTP server to go to its knees if the file size goes beyond 1MB (server CPU goes to 100% for a prolonged period). This seems to be a known issue which IBM does not intent to fix. If anyone cares to try, there is a file upload web service examples available on openntf.org. We have tried using the provided solution to post documents from LifeCycle to Domino and gave up on. Currently I'm developing a generic file upload servlet. I have already done this in the past for a product called Integra for Notes and it worked quite well.
