I use nginx on my server.

PS: if you plan to use vBSEO in future it won't work on nginx or lighttpd.
Also .htaccess don't work on nginx and lighttpd.

NewEra .htaccess dont work on those two. But they both have their own rewrite engines/format. So rewriting essentially works. Meaning, vBSEO would work (if you can rewrite the .htaccess to the nginx/lighty format)
