WriteFreely only runs on domain root

[rowdypixel]

Describe the bug

When running WriteFreely behind a reverse proxy, I configured the proxy to only for the /blog subfolder on my domain. I added https://example.com/blog to config.ini as host, but it still assumes that I am running it on the root. For example, when I make it password protected it redirects me to example.com/login instead of example.com/blog/login upon visiting the home page.

Steps to reproduce (if necessary)

Steps to reproduce the behavior:

1. Run WriteFreely
2. Configure your reverse proxy server to only run on a folder of the domain. I am using Caddy, so my config looks like:

example.com:443 {
        root * /var/www/example.com
        encode gzip
        file_server
        reverse_proxy /blog* http://127.0.0.1:8003  
}

3. Attempt to visit the site.

Expected behavior

The application should use the entire host string to generate its URLs instead of just the host.

Application configuration

• Single mode
• Database? sqlite
• Open registration? no
• Federation enabled? no

Thanks for mentioning this -- it's also been brought up on our forum. Would you be interested in submitting a fix for this?

I will try and implement this. I think the easiest way to do this would be to capture the bind and update the PathPrefix for the static routes and the main handlers.
