So we have to define what to do here. The test fails as:

https://github.com/corazawaf/coraza-caddy/actions/runs/7002992650/job/19047820525#step:6:89

[Fail] could not do http request: Get "http://localhost:8080/response-headers?pass=leak": EOF

This is because before we were returning a content-length but the actual response body was empty (due to interruption) but caddy was returning nil and hence no error https://github.com/caddyserver/caddy/pull/5952/files#diff-a248c9a1ec018edea8b377d155bc1df1a642bf79d00ababb5cdacc6b86c5733dL968.

What is the client receiving now that caddy is returning an error? Should we make the e2e-tester more error-tolerant?

jcchavezs commented 1 year ago

I think we should not fail because this is a legit request, we should just deny it.

Looks good to me! And it is actually an approach that we already used #96 (comment) https://github.com/corazawaf/coraza-caddy/pull/96#discussion_r1287289408 . The interceptor was originally copied from coraza upstream ( https://github.com/corazawaf/coraza/blob/main/http/interceptor.go), can this changes also be ported upstream? Also, vice-versa, we have corazawaf/coraza#923 https://github.com/corazawaf/coraza/pull/923, corazawaf/coraza#925 https://github.com/corazawaf/coraza/pull/925
