[Improvement] Clear DNS cache without having to close Insomnia

[APM-cvshealth]

When testing web service calls across production servers, I often change host file entries to point my machine at a particular web host. I can clear the OS cache, but the insomnia cache requires you to exit and restart the client.

I am told I can wait for 60 seconds, but time is of the essence when I am making production changes and would rather not have to wait.

An option in the UI to clear that cache on the fly would be helpful.

Hi @APM-cvshealth, thank you for reporting this!

This is indeed an interesting improvement/feature request.

This also might link bit with other issues we have, like:

• systemd-resolved synthetic DNS records not being respected #4839
• bug: changing network or switching VPN makes requests stall #4787

FYI @wdawson - probably something we may want to add this year or in near future.
