Uploading with Cloudflare Free Accounts and Reverse Proxy

[tobychui]

Here is the short answer for the most commonly asked questions about uploading files through ArozOS:

Can I Upload Large Files to ArozOS via Cloudflare free accounts?

Answer: YES

The upload logic of ArozOS is designed as follows.

File Size	Upload Method	Temp-file	Fallback
< 4MB	POST (multipart)	RAM	None
< (tmp_space/16) - 1KB	websocket (byte slices)	tmp/	POST
Otherwise	websocket (byte slices)	target disk (.cache folder)	POST

Under normal situation, there will never have a POST request larger than 100MB (the limit of FORM POST size of Cloudflare Free Account at the time of writing) send over to the server. For the tmp folder size, it is recommended to use a fast storage medium (e.g. NVME SSD) with space 4 - 8 times the maximum allowed upload file size.

Can I Use ArozOS Behind a Reverse Proxy Server (nginx / Apache)?

Answer: YES

It is required to proxy both websocket and HTTP request. Here is an example apache config for ArozOS reverse proxy. Edit /etc/apache2/sites-available/000-default.conf and add the following contents.

NameVirtualHost *:80

<VirtualHost *:80>
       ServerName subdomain.example.com

        RewriteEngine On
        RewriteCond %{HTTP:UPGRADE} ^WebSocket$ [NC,OR]
        RewriteCond %{HTTP:CONNECTION} ^Upgrade$ [NC]
        RewriteRule /(.*) ws://<your_arozos_server_ip>:8080/$1 [P,QSA,L]

        ProxyPass / http://<your_arozos_server_ip>:8080/
        ProxyPassReverse / http://<your_arozos_server_ip>:8080/
</VirtualHost>

<VirtualHost *:80>
       DocumentRoot /var/www/html
</VirtualHost>
