So before install of SEF I had URLS of the form:
seclab.uiuc.edu/web/content/view/61/61/
which are now cached in search engines, bookmarked, etc.

Now the URL is:
seclab.uiuc.edu/web/critical-infrastructure/januss-map.html
and if the old URL is used from a search engine or wherever it throws a 404 not found.

Is there a way to add a rule to .htaccess or something that would maintain back compatibilty with those old links by rewriting or redirecting them?

Thanks,
