how many instances???

[Swati Kadam]

how many objects are created when same or different client send 100 requests to a servlet?

[sammeta Phanikumar]

Only one instance(object) is created for one servlet and for each request for this servlet a seperate thread will be created.

[Vishal Matere]

same client, 100 requests: 1 Instance (including SingleThreadedModel servlet)
Diff Client, 100 request: 100 instances (SingleThrededModel servlet)
Diff Client, 100 request: 1 instances (Normal Servlet)

Hi

same client, 100 requests: 1 Instance (including SingleThreadedModel servlet)

Why not 100 instances for 100 requests?

Hi Vishal even I have the same doubt as Pradeep.

why not 100 instances in the case of SingleThreadModel?

[Atul Sawant]

Everytime you send a request it is a new request for the server because HTTP communication is stateless. So, it does not matter if it is a same client or different client. Every request is treated as unique and different.

If you apply singleThreadModel, the instance of that servlet is giving to only one thread (request) at a time. it is NOT creating 100 instances for 100 requests. The instance will be only one, but it will be accessed by one thread (request) at a time.

Hi

i would like to add one thing with single thread model, it is upon vendor implementation whether it allows container to create multiple instances for serving multiple requests or to serve only one request while making others to wait requesting the same servlet .The only point here is that with standard servlet model one instance and multiple threads for serving different requests for same servlet.anyways we are not going to use single thread model.Am i right
