All Implemented Interfaces:

public class HTMLServlet
extends DSpaceServlet

Servlet for HTML bitstream support.

If we receive a request like this:

http://dspace.foo.edu/html/123.456/789/foo/bar/index.html

we first check for a bitstream with the *exact* filename foo/bar/index.html. Otherwise, we strip the path information (up to three levels deep to prevent infinite URL spaces occurring) and see if we have a bitstream with the filename index.html (with no path). If this exists, it is served up. This is because if an end user uploads a composite HTML document with the submit UI, we will not have accurate path information, and so we assume that if the browser is requesting foo/bar/index.html but we only have index.html, that this is the desired file but we lost the path information on upload.
