Win 32 PUT script

I have written a java based voicemail system. Users are able to retrieve,
and delete messages via a java applet. This same applet also modifies and
index to theses messages via a PUT request to Apache 2.0.48 (Win32)
Server. I run the exact same system on a Linux webserver, and everything
runs smoothly. On Windows XP, I run into a problem after storing a few
messages. I get an IOCorrupted Exception. Apon checking the sent index
file, I noticed that the stream is corrupted everytime a 0x1a character
is transmitted. In Windows, this character is known as an EOF (end of
file character). Is there any way to put a stop to windows assuming that
just because a characer says it is an (EOF) that it should fill the rest of
file with 0x1A's. So Far I have told my applet to use Content-type:
application/octet and set the magic config file to try to reconize the file as a
binary. Any suggestions?
