java.lang.Object
   sunlabs.brazil.proxy.JunkBusterHandler

JunkBusterHandler
public class JunkBusterHandler implements Handler(Code)
Remove junk images from web pages. This approach is to take all requests for images that look like ads and instead return a dummy bitmap.

Other approaches to removing ads are to filter the HTML returned and (1) remove the ads altogether or (2) change the href in the ads to point to a different bitmap. The advantage of option (2) is that all ads can be changed to point to the same bitmap, increasing the caching performance of the browser.

Properties:

image
The file to contain the replacement image.
host
The regular expression matching url's to reject. If the expression starts with a '@', it interpreted as a file name (minus the @) that contains a new-line separated list of regular exporessions. See sunlabs.brazil.util.regexp.Regexp for more information on regular expressions.
