Socket receive completely read

I have a socket RPG program that is sending a request to a Java Servlet on
Tomcat.  The send works fine, but I am having trouble making sure I am
getting the entire response; how do I know I have the whole response?

Right now I stop reading after I get two CRLF's(0D 25 0D 25) right in a row.
I then went out to the RFC 2616 only to find that I should probably be
looking for "chunks".  Here is a quote from the site
(http://www.ietf.org/rfc/rfc2616.txt).  Right now I am getting this as the
last sequence of characters -> "0D 25 F1 0D 25 25 0D 25 F0 0D 25 0D 25"

<snip>
   The chunked encoding modifies the body of a message in order to
   transfer it as a series of chunks, each with its own size indicator,
   followed by an OPTIONAL trailer containing entity-header fields. This
   allows dynamically produced content to be transferred along with the
   information necessary for the recipient to verify that it has
   received the full message.

       Chunked-Body   = *chunk
                        last-chunk
                        trailer
                        CRLF

       chunk          = chunk-size [ chunk-extension ] CRLF
                        chunk-data CRLF
       chunk-size     = 1*HEX
       last-chunk     = 1*("0") [ chunk-extension ] CRLF

       chunk-extension= *( ";" chunk-ext-name [ "=" chunk-ext-val ] )
       chunk-ext-name = token
       chunk-ext-val  = token | quoted-string
       chunk-data     = chunk-size(OCTET)
       trailer        = *(entity-header CRLF)

   The chunk-size field is a string of hex digits indicating the size of
   the chunk. The chunked encoding is ended by any chunk whose size is
   zero, followed by the trailer, which is terminated by an empty line.

My question is does anybody have something like this already laid out in
code so I don't have to cover all of the different bases that a host could
possibly send back to me?  Or does somebody have a catch all that will allow
me to always make sure that I have received the entire response?  Or is the
sequence that I have above ("0D 25 F1 0D 25 25 0D 25 F0 0D 25 0D 25") what I
need to be looking for to know that the request has completed in its
entirety?

Thanks,
