what happens first when request goes to container?

[Punit Jain]

i have a question related to servlet.
when we made a request for a page using HttpServletRequest, the container(tomcat), first allocate thread for that request or first it will check weather the requested page is exist in the project or not??

What did the Servlet Spec have to say about this? Hint: if it doesn't say anything, then what happens is completely up to the container implementation.

so you mean it depends on the container.
weather to check for request first or allocate thread for that request..
but if it allocate thread first and if the requested url/page is not found, than it's wastage???

I think it is safe to say that it is the Thread allocated to the request which does the actual lookup since it needs the servlet context for the particular web application.

Furthermore, it is only good practice to have the socket handler Thread hand off to a separate thread as soon as possible.

Why do you care?

Many of the details of what the containers do internally, especially details such as this, don't have much bearing on how to write good web applications.
