I have created one Web Application HelloWorld

which contains one WEB-INF folder and one test.jsp file which prints Hello World Message.


Now i have deployed my web application in tomcat and started the server

at first request server translate the JSP to Servlet initializes the servlet.

now I removed the message Hello World from test.jsp without restarting the server.

and again refreshes the page at browser.

My browaser displays me the updated test.jsp

how does browser identify that jsp has been modified and it has to retranslate the jsp page ?
Is this behaviour garentted ?

It's based on the file modification date. This behavior is server-specific; for Tomcat, check out the documentation of the parameters of the JspServlet in TOMCAT_HOME/conf/web.xml.

tomcat has something called hot swap, this means that there are daemond checking the changes in your app, all time.
