Markus Jelsma commented on NUTCH-2993:
--------------------------------------

To be honest, i am not too happy with the implementation like this. Ideally we 
would regex all outlinks, but that will be even more costly. The crawler still 
ends up in bad sections of the site and further on the www, but with low depth 
settings, it is manageable.

> We do not want some crawl to go deep and broad, but instead focus it on a 
> narrow section of sites.
> This patch overrides maxDepth for outlinks of URLs matching a configured 
> pattern. URL not matching the pattern get the default max depth value 
> configured.
