JSP Program to Delete a Cookie Values

JSP is a dynamic scripting capability for web pages that allows Java as well as a few special tags to be embedded into a web file (HTML/XML, etc). The suffix traditionally ends with .jsp to indicate to the web server that the file is a JSP files. JSP is a server side technology - you can’t do any client side validation with it. The JSP assists in making the HTML more functional. Servlets on the other hand allow outputting of HTML but it is a tedious process. It is easy to make a change and then let the JSP capability of the web server you are using deal with
compiling it into a servlet and running it.
