Goreplay Middlewares

Useful Goreplay middlewares I've come up with.

Compare HTTP

Compare the HTTP responses between the original and replayed request.

• language: Bash

Sample

In terminal 1:

python3 -m http.server 6969

In terminal 2:

python2 -m SimpleHTTPServer 9001

In terminal 3:

while [ 1 ]; do curl -v localhost:6969; sleep 3; done

In terminal 4:

./gor \
  --input-raw-bpf-filter ":" \
  --input-raw :6969 \
  --input-raw-track-response \
  --middleware "/path/to/goreplay-middlewars/compare_http.sh" \
  --output-http http://localhost:9001 \
  --output-http-track-response

input-raw-bpf-filter is only needed for local testing
