Subject: Redirect to root on empty path
X-Git-Url: http://git.archive.openwrt.org/?p=project%2Fluci.git;a=commitdiff_plain;h=5541065793913f8bf201123440e4a827ec779ebd;ds=sidebyside

Redirect to root on empty path

* Prevents an empty Location header
* Useful in environments where build_url() could return an empty string (such as http server rewrites requests to /cgi-bin/luci)
