You could do that with flowbits, but it'd probably be a good load on snort.
Worth looking into though.
Are you looking to know just about the error after a known attack, or
about all errors or non-error returns?

Hi, does stream4 collect both directions of a flow? I.e. is it possible
to have a set of signatures that tags a flow (standard http attack) and
then watched for a 200 response from the web server.
I assume that the answer is no otherwise we would be diong this as a
matter of routine.
It long ago got to the stage where I ignore the flood of altert
generated by people poking at our web servers. The fact that some poked
at our web server is of no interest at all. The fact that someone poked
at the web server and the server did not return an error is of interest.
Perhaps this could be built into a preprocessor that returns the status
on an http connections.
