Trouble with CFLOCATION and Proxy Servers

Question

Hi,
Trying to troubleshoot an annoying issue and wondering if
anyone has had any experience with this - haven't had much luck
Googling for info. Using up-to-date CF 6.1 and current version of
Apache 2.0. Client is accessing our CF webapps via a clustered
proxy server/firewall archicture. Each time client users HTTP POST
through one of our applications, the page they are redirected to
only displays a small portion of unprocessed raw source page
content, the remaining page content never seems to make it to the
client's browser. The only way they can a valid version of the page
is to refresh the browser. I verified that small portion of raw
source content is returned by the application during these
redirects using an HTTP sniffer, however my office PC still
redirects to the correct page. We are using <CFLOCATION> tags
to move users between pages after submitting.
I suspect this problem has to do with their proxy server(s)
holding HTTP 302 responses to the literal standard, which
(paraphrasing) basically states that while the URI has been moved,
it is up to the client to continue the actual redirect. I believe
HTTP 303 responses would be the "correct" implementation. Having
said that, we've never run into this issue with any other client
users before.
Has anyone ever run into similar issues before? Any help is
greatly appreciated.
Thanks,
DTS

Replace
byte[] buf = null;with
byte[] buf = new byte[ 256 ];Other problems may happen if this sample was not tested properly.
The problem is that the DatagramPacket requires you to supply a non-null buffer, as per:
DatagramPacket
public DatagramPacket(byte[] buf, int length)
Constructs a DatagramPacket for receiving packets of length length.
The length argument must be less than or equal to buf.length.
Parameters:
buf - buffer for holding the incoming datagram.
length - the number of bytes to read.
