Hi,
i had a similar query, i want to store the entire response for my book
keeping , before it is flush out on to socket connection.
if while storing the response(using a cache to store) any IO error occurs ,
i want to send out 500 error instead.
Any thoughts on how can this be achieved?

Whatever code is writing to the cache needs to just hold onto the
exchange and send an error response as required.

hi Stuart,
I have a ResponseCommitListener added to my handler, I want this to write
to the cache, so that my reponseWrapper will take of the error handling if
the ResponsecommitListener faces any error while storing the response to
cache.
I understand HttpResponseConduit constructs the headers and then pushes the
response.
But the confusion is, how will i get a access to response Headers and body
in the my ResponseCommitListener?
My approach is valid? if not ,any suggestion?

You have access to the exchange, it is passed into the ResponseCommitListener.

Hi Stuart,
i am new to Undertow code, Can you please elaborate.
yes, The exchange will be passed to the ResponseCommitListener, but From
exchange i cannot get the response content directly ,correct? as there is
no method to get the Response body like getResponseHeaders.
so i would need something like a conduit inside my ResponseCommitListener
to get a handle on the response content?
Any other straight forward way to get the response content using exchange
object?
Thanks for all the help.

You can use the newish
io.undertow.conduits.StoredResponseStreamSinkConduit, however you will
need to be on a very recent version of Undertow (or you can just copy
the code into your project).
It won't be available in ResponseCommitListener though, as this is
called before any content is written. To be honest I am not really
sure what you are trying to do. In general if you can an IOException
when writing the response there is nothing much you can do other than
terminate the connection.

Thanks for suggestion.
To put it into simple terms ,what i am trying to do is,
a). I want to store all the response(headers+body) into cache,
i.)if this is successful ,then begin writing the response to client.
ii.)if store to cache fails, then write failure message(maybe 500
error message) to client.
b.) if while writing the response(failure message or success actual
response) to client there is an IO exception, then Undertow already has the
mechanism of terminating the connection, which is fine.
basically, i want to store the entire response to the cache before the
first byte is written on the socket.
Ultimately, The Cache will contain all the responses which are processed
successfully, which can be used for book-keeping.
Will StoredResponseStreamSinckConduit help me achieve the above?
