This is a servlet filter and some.
It watches referer. If unknown referer URL found, it gets the URL page and analyze the page. If the link exists (fake referer is usual), it quotes the text around the link. The quoted text is 'fragment'. Those information (linked page and fragment) are stored to RDB.
Many blog tools generate many pages from one entry. But, Referer Hound identifies the same fragment in many pages. You will get one fragment for one blog entry.
If your page is jsp or servlet, you can insert the information to your page dynamically.
RSS feed servlet is available. It feeds newly arrived referer URL and the fragment.
Requirements:Servlet container (Servlet 2.3 and JSP 1.2)
Referer Hound is a part of Figaro.
