How to force Apache Bench to use the IP addresses specified in / etc / hosts?

Question

I am using ApacheBench for load testing. I would like ab to resolve the host name using the IP address specified in / etc / hosts on my Mac. How can I make it? curl has the --resolve option to do just that, as stated here . I am looking for something similar for ab.

Answer 1

Think of it differently: you can say that Curl hit the IP address, and specify a title Hostto start the domain you need.

curl example.com
curl --header "Host: example.com" 93.184.216.34

The same method works abusing a flag -Has such

ab -n 10 -c 10 http://example.com/
ab -n 10 -c 10 -H "Host: example.com" http://93.184.216.34/

Hope this helps.
