Project: Nutch
Issue Type: Bug
Affects Versions: 1.3, 1.4

---------------------------------
Here is my setup. Page1 (only seed) has links to Page2 and Page3, both of which redirect to Page4. So I guess Pages 2 and 3 will be in the same fetch list. But I don't see Page4 parsed twice.

---------------------------------------
I have tried running nutch with a sample site with two different urls redirecting to a common resource and http.redirect.max > 0.
I could not find any clues, from hadoop.log, where the common resource is parsed multiple times.
Could some one please explain the exact scenario that causes this bug.

Yes I was doing so. Thanks. I tried with fetcher.parse. Now it fetched Page4 twice.

--------------------------------------
Ah, i assume you're doing the parse step separate from the fetch job? Try running the fetcher with fetcher.parse.

--------------------------------------
Make sure you have two pages pointing to a different URL but redirecting to the same. If URL's X and Y are in the same fetch list and redirect to the same URL, it will be followed twice.
