Encounter a problem while setting up diffy tutorial... #20

hi,

i encountered a problem while setting up the tutorial... and that is probably due to the header "Host" sent by the diffy.

the tutorial has 3 urls,

  1. http://http-candidate.herokuapp.com
  2. http://http-primary.herokuapp.com
  3. http://http-secondary.herokuapp.com

and here is the traffic from diffy,

  1. http://http-candidate.herokuapp.com 174.129.192.57 GET / HTTP/1.1 Host: localhost:8990 User-Agent: curl/7.43.0 Accept: / Canonical-Resource: Html
  2. http://http-primary.herokuapp.com 174.129.192.57 GET / HTTP/1.1 Host: localhost:8990 User-Agent: curl/7.43.0 Accept: / Canonical-Resource: Html
  3. http://http-secondary.herokuapp.com 54.83.197.202 GET / HTTP/1.1 Host: localhost:8990 User-Agent: curl/7.43.0 Accept: / Canonical-Resource: Html

it seems 1. and 2. are in the same instance, and depend on "Host" to determine the response, but the header "Host" from diffy is "localhost:8990", so the services always return 404...

removing the filter of Host from server or using the diffy proxy to change Host to http-xxxxx.herokuapp.com (the value from example.sh) may help.

I'm also experiencing this issue, look like diffy resolve hostname into IP before sending the request

How do you see the traffic from diffy? I also get the same response(404) as yours... How to solve this issue?
