The application doesn't work well behind an http proxy #152
Description
First of all great work, I like the simplicity of the application and what it provides.
However I would like to request a change. When the TeslaBleHttpProxy sits behind an http proxy on a path that's not the root (e.g. /tesla-ble-proxy). The forms and redirects dont' work well.
For instance when going to the dashboard (e.g. /tesla-ble-proxy/dashboard) everything looks fine. However the forms themselves submit to the root (e.g. /send_key) missing the prefix /tesla-ble-proxy. This can be "fixed" by changing the form action from /send_key to send_key (remove the slash). However the redirect after the submit still goes to /dashboard.
Can we make the application aware of the path it's currently called from and make forms and redirects work even when the application isn't hosted in the root?
