[Laszlo-dev] Flash file upload

[Henry Minsky]

I don't think you get any access to return values from the server.

There are a couple of notes on this page that are also eye opening

http://livedocs.macromedia.com/flash/8/main/wwhelp/wwhimpl/common/html/wwhelp.htm?context=LiveDocs_Parts&file=00002204.html



"If the file to be uploaded is bigger than approximately 10KB, the Windows
Flash Players will first send a test upload POST with zero content prior to
uploading the actual file in order to verify that the transmission is likely
to be successful. The second POST will contain actual file content. For
smaller files, the Flash Player will do a single upload POST with the file
to be uploaded.

The Mac players currently do not do test upload POSTs."


There are also reports of bugs in the way it formats the upload HTTP
request, and I believe are I have seen those bugs, the uploading doesn't
work with the apache Java library that is supposed to accept uploads. It
does work with a Java library I found called
multipartrequest.jar from http://www.andreasklimke.de/webdev/misc.html
