`redirect_from` is adding `site.baseurl` to `site.url` (Duplicates the baseurl on Github Pages)

[David00]

Hi, I have a site hosted on Github pages, and redirect_from is appending the site.base_url after the site.url.

I'm simply attempting to redirect requests that go to /docs/latest/page.md to /docs/v0.3.0/page.md.

My site's baseurl is /rpi-power-monitor, and the site.url is https://david00.github.io/rpi-power-monitor. When I use redirect_from, I end up getting redirected to https://david00.github.io/rpi-power-monitor/rpi-power-monitor.

I've setup a demo of exactly what I mean, which contains some details about the page's front matter, the values of site.url and site.baseurl, and a few redirect_from values that I've tried:

https://david00.github.io/rpi-power-monitor/docs/v0.3.0/test.html

If you want to see my site's _config.yml and Gemfile, they are here in the docs branch: https://github.com/David00/rpi-power-monitor/tree/docs

Please let me know if you need any more info!

Thank you.

Technically, stitching site.url with site.baseurl is expected and by design because that is what Jekyll considers as leading components of an absolute URL.

However, the duplication of the /rpi-power-monitor in your case is due to configuration mismatch.

GitHub Pages probably sets the --baseurl Jekyll CLI switch under the hood which is evident in the /docs/v0.3.0/test.html render (in contrast to what is in your _config.yml). To rectify, edit your config file to have (which is actually the correct way):

url: "https://david00.github.io"
baseurl: "/rpi-power-monitor"

That worked!!

That should have been so obvious to me... but it wasn't. I actually tried the opposite edit of setting baseurl: "", but that broke all of the styling.

Thank you so much for taking a look and providing context and a solution!
