Question

i put
AllowEncodedSlashes On
inside /etc/apache2/apache2.conf and inside /etc/apache2/sites-available/default but still got 404 page after access url with encoded slashes

Answer 1

I was searching a lot for this. But can't find a clear answer for Ubuntu 14.4 and Apache 2.4.7 . I figured it out. Here's what I did:
Go to /etc/apache2/sites-available
Open the 000-default.conf file.
add AllowEncodedSlashes NoDecodeinside the <VirtualHost> tag
Save and restart Apache.
** apache2.conf modification is not needed. Modify only 000-default.conf file and not default-ssl.conf

Answer 2

You should use
<VirtualHost *:80>
AllowEncodedSlashes On
ProxyPreserveHost On
ProxyRequests Off
ServerName www.domain.com
ServerAlias domain.com
Redirect permanent / https://example.com/
</VirtualHost>
If your domain is secure with ssl certificate then you shuold also use with 443 port
<IfModule mod_ssl.c>
<VirtualHost *:443>
ServerAdmin webmaster#localhost
ServerName example.com
DocumentRoot /var/www/html
ProxyPreserveHost On
AllowEncodedSlashes On
ProxyRequests Off
ProxyPass / http://localhost:3000/
ProxyPassReverse / http://localhost:3000/
