threadlocal variables in a servlet

Question

Are the threadlocals variables global to all the requests made to the servlet that owns the variables?

I am using resin for the server.

Thanks for awnser.

Answer 1

Using ThreadLocal to store request scoped information has the potential to break if you use Servlet 3.0 Suspendable requests (or Jetty Continuations) Using those API's multiple threads process a single request.
