Hi Friends,

Are Request and Response Objects thread when they are used out of the service() method..

What does this mean..and what are the situations the programmer has to be precautious when developing..

and is true that the Request and Response Objects shouldn't be referenced by objects executed by other threads?

Yes. These objects are created and references within a single thread. Ergo, no thread-safety issues.

It means you don't need to worry about any synchronization issues with these instances.

Absolutely. Doing so would introduce all manner of threading issues.
