Hi,
This is a combination of a wish and a question. Our users are looking to upload files of sizes ranging between 1MB and 1GB. We use ColdFusion on Windows servers. If even two users concurrently use the ImageUploader tool and upload files of a GB each, this might bring the system to its knees. This is because the file upload procedure in ColdFusion reads the entire file into memory and then writes it on disk. Are there any methods to cut up large files into much smaller bits and transfer them to the server? Then at the server-side, they would be assembled together and the upload would be processed as before.

We already use the separate upload mode. It does help if you are transferring a large number of smaller files. We use the Java applet, by the way.

Any ideas?

Thanks
Fedor

Hello,

It is good idea. We can implement it as a custom feature. Please contact us at sales@aurigma.com for more info.
Best regards,

Fedor,
A question, though: would this also involve additional work on the server side for ColdFusion? I mean, if you do implement a custom feature, would this just be on the applet side or do we have to figure out how ColdFusion sees the incoming bunch of sliced binary data? Forgive my ignorance in the matter.

Yes of course. You will have to change your server code to assemble file parts from different upload requests.
Sincerely yours,
