JSP Response setDateHeader
In this tutorial you will learn about setDateHeader() method of HttpServletResponse interface.
HttpServletResponse setDateHeader() method is used to set date with the specified header name. Using this method in the header date value can be associated with the header name. New value of header will be overwrites if it is already been set.
Syntax :
