No idea, sorry. Maybe the Flashplayer will handle this better in the future.

Hi Sönke, do you think that there’s a chance to avoid the ui freeze while
calling “loader = new URLLoader( request );”? Small chunks minimize the freeze but the
upload takes much longer. Larger Chunks are good for upload speed but unfortunately the air app
freezes while calling the URLLoader. A native proccess for uploading would be great, but is it
possible to call an air app as native proccess? Or how did you solve the problem?

Each variable has its own content-disposition. Have a look at the method createVariable.

Hi Sönke, but how do you separate the parameters and the values from the “raw” file data?
I’ve monitored an upload request with Charles (Chunk size 20B, request 2 of 5). The file content comes together with the filename..? Shouldn’t there be an extra content-disposition chapter? Or how did you handle the requests in your case? Thanks, Jo

Thanks for the feedback! Unfortunately I can’t share the server side code but in this case it was Perl.

Hi Sönke,
what do you use on server side? A servlet? Maybe you can post some code?
Would be great!
Thanks! Jo

Must have been a hickup in my browser Sönke, the page comes through fine now, sorry!

Hi Sönke,

Your post doesn’t seem to be complete, and the download link to GitHub for your UploadFile class doesn’t work. I also can’t seem to find this class in any of your GitHub repo’s.
Could you please tell me where I can find the code?

Thanks!

Sven
