The Referer
header indicates which document referred to the one currently
specified in this request. This helps the server keep track of
documents that refer to malformed or missing locations on the server.
For example, if the client opens a connection to www.ora.com at port 80 and sends:
GET /contact.html HTTP/1.1 Host: www.ora.com
The server may respond with:
HTTP/1.1 200 OK Date: Tue, 04 Apr 2000 02:22:47 GMT Last-Modified: Sat, 18 Mar 2000 17:18:22 GMT ETag: "134e8-b2a-38d3ba5e" Accept-Ranges: bytes Content-Length: 2858 Connection: close Content-type: text/html <h1>Contact Information</h1> <a href="http://sales.ora.com/sales.html"> Sales Department</a>
The user clicks on the hyperlink and the client requests sales.html from sales.ora.com, specifying that it was sent there from the /contact.html document on www.ora.com:
GET /sales.html HTTP/1.1 Host: sales.ora.com Referer: http://www.ora.com/contact.html
