The disadvantage of a simple overlap check is that, on a mismatch, you don't know which one of the two non-matching chunks to consider wrong. You have to discard both chunks to be sure. This way, an evil source can force you to discard already downloaded parts. An intelligent way to detect and discard evil sources must include quite "stateful" (and thus complex) logic, unfortunately. bye, Hauke Hachmann ------------------------------------------------------------------------- Using Tomcat but need to do more?
