Static file directories should append trailing slash to URL (BB-2909)
go to two separate places. This violates my expectation (and is hurting my Google search traffic for "markdown css"). I also tried adding a static file called markdowncss that would add a 301 redirect to the directory with the trailing slash, but it looks like you can't have a file and a directory with the same name together (at least easily).
In nginx, it looks like you have to add this setting:
rewrite ^(.*[^/])$ $1/ permanent;
to append the trailing slash to URL's that don't already have it. For more see this Stackoverflow question at http://stackoverflow.com/questions/645853/add-slash-to-the-end-of-every-url-need-rewrite-rule-for-nginx.
