 title: Overview

-TBD
+Mongoose uses non-blocking DNS resolver. For each name to be resolved,
+it first checks the `/etc/hosts` file (or, `hosts` on Windows).
+If the entry is not found there, then the `8.8.8.8` DNS server is queried.
+When IP address is found, Mongoose proceeds with making the connection
+with the resolved IP address.

 title: Digest Authentication

-TBD
+Mongoose has a built-in Digest (MD5) authentication support. In order to
+enable Digest authentication, create a file `.htpasswd` in the directory
+you would like to protect. That file should be in the format that Apache's
+`htdigest` utility.
+
+You can use either Apache `htdigest` utility, or
+Mongoose pre-build binary (https://www.cesanta.com/products/binary)
+to add new users into that file:
+
+```
+mongoose -A /path/to/.htdigest mydomain.com joe joes_password
