Mark Datagrid column sorting links as "nofollow".
Review Request #11113 — Created Aug. 2, 2020 and submitted
Search engine crawlers have a tendency to follow versions of datagrid
pages with different column sorting, which can trigger a lot of load on
a server. While this can be partly mitigated with a
best to inform the crawler that this isn't a link it really wants to
To help avoid indexing these pages, these sorting links now have a
rel="nofollow"attribute. Most of the big crawlers support this to
some degree, though some will still crawl it regardless. Still, it
should cut down load on public servers a fair amount.
Verified the attribute on all the Review Board datagrids.
