Subject: Chunk size & RFC
Date: Wed, 18 Apr 2001 17:04:54 +0200

Hello,

I'm a French student and I'm looking for some answer about the size of
chunks in Apache's responses to requests.  Indeed, I'm sending a GET
request on a php3 file hosted by my Apache Server, which respond with
a "Encoding-type : chunked" message.  The size of the file is small
(<256bytes), and the response fits in a single chunk.

But the client I use can't read it : The Apache Server keeps adding
spaces after the "chunk-size" slot.  In fact, my client must follow
the Http RFC2068, and can't read spaces after a chunk-size (waiting
for ";" or "CRLF").  The interesting thing is that the Server seems to
write 3 chars in this slot everytime he sends a response, even if the
message is shorter.

So my client can work for response between 256 and 4095 bytes, what is
not enough for an application I'm trying to build.  I've been trying
to configure Apache so that the problem disappears, but I haven't
found any good configuration yet.

Could you give me a solution...?
I'm enclosing samples : the most simple php page I could GET, and the
Http response from the server.

PHP PAGE : 
<HTML>
  <BODY>
<?php
        echo "variables recues: X1=".$x1." et X2=".$x2;
?> 
</BODY>
</HTML>
