Do you have to specify anything special when you use your browser with
a web app via a load balancer?

JMeter sends the same (or similar) HTTP requests as a browser, so the
load balancer and web app cannot in general tell the difference
between JMeter and a browser.

However, JMeter generally represents multiple browsers.

This may have some bearing on load balancers, depending on how they work.

If they rely on variable DNS responses (i.e. hostname resolves to
different IPs each time the resolver is called), then this may not
work with JMeter, as I think Java will only resolve the name once. The
OS may also cache DNS name resolutions.

You need to check the documentation for perlbal.
