Question

I have a basic question on Tomcat thread creation. Does every browser instance run on a single thread or does it spawn multiple threads to process a single browser instance request?

I am taking a reference of the current thread in the code and calling the activecount method and it is showing 20 which indicates 20 active threads. So I have doubt from where this value is configured. Is there any parameter to set the active threads per

while (iter.hasNext()) {
  GrammarSection agrammarSection= null;
  try {
    agrammarSection = (GrammarSection) iter.next();
  } catch (Exception e) {
    System.out.println("DDD if it come in exception "+Thread.currentThread());
    System.out.println("DDD if it come in exception "+Thread.activeCount()); //IT PRINTS 20

Answer 1

Tomcat creates a pool of threads. Typically, one HTTP request is served by one thread.
