Using HTML5 mode requires URL rewriting on server side, basically you have to rewrite all your links to entry point of your application (e.g. index.html). Requiring a <base> tag is also important for this case, as it allows AngularJS to differentiate between the part of the url that is the application base and the path that should be handled by the application. For more information, see AngularJS Developer Guide - Using $location HTML5 mode Server Side.

How to: Configure your server to work with html5Mode1
When you have html5Mode enabled, the # character will no longer be used in your urls. The # symbol is useful because it requires no server side configuration. Without #, the url looks much nicer, but it also requires server side rewrites. Here are some examples:
Apache Rewrites
<VirtualHost *:80> ServerName my-app DocumentRoot /path/to/app<Directory /path/to/app> RewriteEngine on # Don't rewrite files or directories RewriteCond %{REQUEST_FILENAME} -f [OR] RewriteCond %{REQUEST_FILENAME} -d RewriteRule ^ - [L] # Rewrite everything else to index.html to allow html5 state links RewriteRule ^ index.html [L]</Directory></VirtualHost>Nginx Rewrites
