Also, XMLSocket/Socket cannot connect to ports below 1024, without a special
policy server. If they cannot modify the script, I am guessing that
installing a separate socket server to hand out policy files is also not
possible.
See more info here:

What I don't know how to do is read a
local file in such a way that I'd be able to use its raw data as a
string to send to a socket.
Unfortunately this is not possible when running from a browser. Otherwise it
would open potential security holes. (Imagine some random SWF reading data
from your disk)

Re: [Flashcoders] Sending binary data to server - NO HEADERS
It seems like you are doing a lot of work, because of a poorly-designed server script. I would really try and see if you can get permission to modify the script. If not, perhaps you can have a 'bridge' script, that recieves the data from flash, formats it correctly for the other script, then forwards it. All the flash 8 methods of sending data to server that I can think of, will have some sort of header or data format that will need to be processed first. -David R On 3/5/07, Carlos Saenz <[EMAIL PROTECTED]> wrote: I am trying to send binary data to a server side script which takes a variable called file, and saves it as a binary file. so if I have a variable in my flash movie "myfile", with a value of "asdf", and I send that to the server, it will make a file on the filesystem called "myfile", and the contents of it will be asdf Now, the trick is to send the script an image or video file.

Re: [Flashcoders] Sending binary data to server - NO HEADERS
carlos, what language is the other script (not php) written...i had a similar problem using java...the issue is that there are two headers being sent...one without content to make sure the addres is valid and a second one after with the data..so you need to set up a condition that doesn't do anything when there is no content and handle the one with the content data in it hope this helps On 3/5/07, Carlos Saenz <[EMAIL PROTECTED]> wrote: I am trying to send binary data to a server side script which takes a variable called file, and saves it as a binary file. so if I have a variable in my flash movie "myfile", with a value of "asdf", and I send that to the server, it will make a file on the filesystem called "myfile", and the contents of it will be asdf Now, the trick is to send the script an image or video file.

[Flashcoders] Sending binary data to server - NO HEADERS
I am trying to send binary data to a server side script which takes a variable called file, and saves it as a binary file. so if I have a variable in my flash movie "myfile", with a value of "asdf", and I send that to the server, it will make a file on the filesystem called "myfile", and the contents of it will be asdf Now, the trick is to send the script an image or video file.
