Fonts return 404 in PUI under a prefix

[payten]

With all the prefix buzz, I revisited it all and came across a bug whereby the path to custom fonts and font-awesome is incorrect and returns a 404 for the ArchivesSpace PUI.

To replicate, you can use a Docker image to be your proxy (unless you're a lucky ducky and have apache installed already).

ASpace Server IP: 192.168.1.14
Proxy IP (Docker Image): 192.168.99.100

Setup ArchivesSpace
Fake a domain:
$ sudo vim /etc/hosts
192.168.99.100 proxy.payten.com

$ wget https://github.com/archivesspace/archivesspace/releases/download/v2.1.1/archivesspace-v2.1.1.zip
$ unzip archivesspace-v2.1.1.zip
$ vim archivesspace/config/config.rb

AppConfig[:frontend_proxy_url] = 'http://proxy.payten.com/staff/'
AppConfig[:public_proxy_url] = 'http://proxy.payten.com/public/'

$ archivesspace/archivesspace.sh

Setup Apache
$ docker pull linode/lamp
$ docker run -it --name aspace-proxy lamp
This will give you a shell in the docker instance:
docker$ apt-get update
docker$ apt-get install vim
docker$ vim /etc/apache2/apache2.conf
Add:

IncludeOptional mods-available/proxy.load
IncludeOptional mods-available/proxy.conf
IncludeOptional mods-available/proxy_http.load

docker$ vim /etc/apache2/mods-available/proxy.conf

<IfModule mod_proxy.c>
ProxyPass /staff http://192.168.1.14:8080/staff
ProxyPassReverse /staff http://192.168.1.14:8080/
ProxyPass /public http://192.168.1.14:8081/public
ProxyPassReverse /public http://192.168.1.14:8081/
</IfModule>

docker$ apache2ctl restart
