Hi

I'm not sure this is the right place to ask this, but since this is definetly client side I hope it's not a problem...

some background info's:

I have an embedded webserver to which I want to send a file so that he can forward it to a serial device (the device is attached to the server ...).

The problem (or actually one of many) is, that I can't send the whole file to the server, but I have to cut it in bits of 100bytes so he can process them one at the time (the server has no need to store these pieces).

I thought to do this using XMLHttpRequests

my question:

Using Google and forum searches I haven't yet found a way to load this file (which resides on the clients PC) in order to prepare it for piecewise transmission.
Obviously I can't just access a file on the clients computer for security and privacy reasons. However, it should be possible (so I hope) to let the user search for a file (like a 'browse' button) and then for me to use this file. Does anybody know how this is done?

The whole thing should work on firefox as well as IE
