This paper describes the method of realizing anti-theft chain by jsp. Share it for your reference, as follows:

Recently, I encountered the problem of chain theft, that is, copying one url address and accessing it in another place.

index. jsp page


<html>
 <head><title>Simple jsp page</title></head>
 <body>Place your content here
 here is index jsp
  get header info
 <a href="a.jsp">a.jsp</a>
 </body>
</html>

a. jsp page


<html>
 <head><title>Simple jsp page</title></head>
 <body>Place your content here
 here is a. jsp
  get header info
 <%=request.getHeader("Referer")%>
 <%if(null == request.getHeader("Referer") || request.getHeader("Referer").indexOf("yourdomain.com") < 0){%>
    Be honest in life 
 <%}else{%>
  Legal access 
 <%}%>
 </body>
</html>

That is to say, it can be accessed from inside, and it is forbidden to paste the address directly in another browser

I hope this article is helpful to everyone's JSP programming.
