In fact, in your case, it is expected to have no compression. You abort the
request analysis, skipping this way the response analysis. It is equivalent
to
what happens with an "http-request deny". The compression is performed
during
the response analysis.
To be able to compress a response returned from a lua script, you must use a
service instead of an action that aborts the request. A lua service is an
applet
that is equivalent to a server. So the response analysis is performed and
the
response is no limited to one buffer. To do so, you must use the
"use-service"
action.
Unfortunately, I need to use an action in this case because I want the original
backend to be called if my action does not return txn:done().
I also looked at implementing gzip compression at lua level but even if it works
locally, It's quite difficult to package gzip support to official docker images
used in kubernetes ingress controller.
Another solution is to set a variable in your lua action to redirect the request
to a lua service if it is set. For instance:
http-request lua.myscript if !static_content
http-request use-service my-service.lua if { var(txn.intercept) -m found }
