Warning -> n00b here!
For some time now I am learning the tools for pen-testing but I am still complete n00b. I have installed Metasplitable2 in another computer on local network and I am running Kali as VM on my computer. So I have started BurpSuite to capture traffic to :8180/admin/ on Metaspoitable2. But to my surprise I saw (apart from the expected traffic) POST requests to ocsp.digicert.com. My Kali installation is default (no new SW installed). So my question is: why is Kali browser making POST requests to ocsp.digicert.com. Is this normal?
