Hi Christopher,
Thank you for you answer. The first case you described fits to me. If I
face any issues I will write to this thread.

Is the TXN.done(txn[, reply]) function in haproxy 2.6 what I am
looking for ?

In the lua HTTP class did not find a method allows to override
response body. May be it is possible via some other methods ?
If not, are there any reasons should prevent me to write it ?
Hi,
It depends on what you want to achieve. If you want to return a custom
response, you can indeed register a lua action and call it in an
http-response rule. You can create a Reply object with some original
response headers, if necessary, and with a custom body. In this case,
TXN.done() should be used.
However, this solution is limited to one buffer. You cannot stream the
response payload. In the same way, you must wait for the response body
to rewrite it. But only if the whole response fits in a buffer. With
this solution, it is not possible to rewrite a too big response body.
If you want to rewrite a large response, you must write a lua filter.
It is more difficult. The API is a bit rough. But it is more versatile.
