Hi,

it means that if it is set to true, same Http handler instance (Page class
is one example of HTTP handler) will be reused for multiple, non-concurrent,
requests.

So if you set it to true and HTTP handler uses some sort of state, you need
to be able to clear the state so that handler works similarly for all
requests. That can get hard.

Point with the property is to of course, provide mechanism to optimize
request processing.
