ZAP does not proxy on localhost running application

[Albert]

I am trying to proxy my browser request to ZAP, it works fine but when I try to access WebGoat which runs on my localhost: 

localhost:8080/WebGoat/login.mvc 

it does not list the request, seems is not proxying. If i try any other URL (www.google.com) in another browser tab it does. 

So the browser is proxying properly on port 8081 as I set it like that in both the ZAP and browser network properties. 

Why it does not proxy the request the browser sent to access my localhost but does proxy any other url?

Any idea?

Just to mention as well that Firefox, ZAP and the WebGoat are all running on a VM

Hi.

Did you remove "localhost, 127.0.0.1" from the option "No Proxy for" in
the "Connection Settings" dialogue?

Browsers usually require extra steps/configurations to proxy "localhost"
traffic.

Best regards.

I did a simple thing: added this into  /etc/hosts
127.0.0.1       samir.com

and ran(in mac terminal): sudo killall -HUP mDNSResponder

localhost requests are not captured by ZAP although I had remove localhost from "No Proxy for".

Are there any other settings which need to make for it?

[Peter Hauschulz]

as long as ZAP is listening on localhost:7777

what are your settings in ZAP?

[thc...@gmail.com]

Not sure which version you are using, Firefox 67+ no longer proxies
"localhost" by default, you need to set the preference
"network.proxy.allow_hijacking_localhost" to "true".

If you launch Firefox from ZAP it will have all required settings to
proxy correctly through ZAP.

Note that you're answering to a 5 years old thread, things changed in
the meantime (one has to configure other setting to proxy localhost, as
mentioned in a previous post).

Best regards.
