Question: Plot piecewise continous periodic function

If we have a piecewise continous 2*Pi-periodic function

h(t)=e^(2*t) when 0 < t < 2*Pi

How can we plot it? It should look something like this:

 

Periodic plot

 

I.e. I want to be able to just set an interval and then it automatically plots the function with the specified periodicity.
