Question

session.setAttribute("referrer", "linkshare");

This is how it is mentioned in some code.
How does this work??

Answer 1

this just sets an Object in the session …( that is the scope of the variable is maintained for that session )

syntax : session.setAttribute(attributeName,attributeValue);

while getting (ObjectType)session.getAttribute(attributeName);

for example setting and getting an object of type string

HttpSession session=request.getSession();
String name="abc";
session.setAttribute("nameSession",name);
String sname = (String)session.getAttribute(name);
