TCP ACK/RST packets with data in the Reset Cause

Subject: TCP ACK/RST packets with data in the Reset Cause
Date: Tue, 10 Jan 2006 11:06:03 -0500
Has anyone ever seen TCP RST packets being sent from clients to web
server with a "Reset Cause" containing the HTML that was in the packet
that they are responding to?

For example a browser client is getting a 404 error returned from my
webserver but right after this I am seeing a CP ACK/RST packet from
the client with the 404 HTML in the packet.

When I look at the packet in Ethereal it shows the HTML in a field
called "Reset cause".

These packets are causing my IDS to go nuts.
