HTTP PUT to truncate a file.

[Ben Timby <btimby@xxxxxxxxx>]

I am working with WebDAV on apache and I have figured out how to use
the Content-Range header to append to a file.

Request 1:
HTTP/1.1 PUT /file
Host: node0
Content-Length: 1

a

* /file now: a

Request 2:
HTTP/1.1 PUT /file
Host: node0
Content-Range: 1-4/*
Content-Length: 3

aaa

* /file now: aaaa

Now I would like to truncate a file...

HTTP/1.1 PUT /file
Host: node0
Content-Range: 2-4/*
Content-Length: 0

But this does not work. Any pointers? I can truncate the file to 0
bytes easily, but I want to truncate it to an arbitrary length.

Thanks.
