Set a user-agent

[wheresalice]

indielogin.com is pretending to be a Firefox browser when it fetches my website during login. This fails because it is detected as a bot, but it doesn't provide any distinguishing user-agent string to be able to allow the requests.

It's a long time since I've worked with PHP, but it looks like it takes the user-agent from a .env setting, which is presumably being overridden in production.

Please set a more specific user-agent so that we can allow these requests.

The user agent config in the .env is currently used when this project makes HTTP requests mainly to GitHub. The IndieAuth request is actually coming from a separate library that is setting the Mozilla user agent string:

https://github.com/indieweb/indieauth-client-php

I will need to first update that library to accept a configurable user agent string.

Ironically, the reason that project uses a browser-looking user agent string in the first place is because a lot of websites were blocking it when it sent a request with a custom user agent string 😂
