FileReference and random imageFile

Hey I am uploading a file to an asp script using Flash cs3, FP 8 as2.

my upload seems to work fine, but when downloading the file I receive a -1, now this is all created by the backend developer (who wrote the asp), this isn’t my question.

when i upload my sample.jpg image and he receives it, he changes the file name to something random and returns it back to me.

my question is how can I check what is being sent back, I am using onUploadCompleteData to get a -1 back, but is there anything else to use?

I suppose this is a question I should be asking the backend dev.

but maybe there’s some insight here.

anyways, thanks for the help.
