mod_http_index: Hide http apps that haven't set a title by default This setting was meant to default to this but by some mistake defaulted to true. Apps that haven't set a title might not be meant to be user facing, so hiding them makes sense.

This module lets you block connections to any remote servers not on a
whitelist.

``` {.lua}
s2s_whitelist = {
    "example.org",
}
```
