Wireshark · Wireshark-users: [Wireshark-users] localhost versus url

[Tony Anecito <adanecito@xxxxxxxxx>]

Hi All,

I was running some performance tests last week and noticed with the client app 
running on the same server or apache web server machine the response time was 
much better when using localhost in the url versus my domain name. I assumed 
somehow the connection is bypassing my router and connecting to the apache 
process directly. Is that so and if not what should I see on Wireshark if 
anything? Or is even the tcp/ip stack short circuited?

Thanks,
-Tony
