Interaction between redirects and trailing slashes

[jeanas]

Details

• Read the Docs project URL: https://readthedocs.org/projects/rtd-redirects-test/
• Read the Docs username (if applicable): https://readthedocs.org/profiles/jeanas/

Expected Result

There are two redirects on this test project (which is a copy of the Python Packaging User Guide where I'm experimenting with redirects):

• Page redirect: /additional → /guides/
• Page redirect: /current/ → /guides/tool-recommendations/

I expected redirects to work regardless of whether the URL has a final slash or not.

Actual Result

With this,

• https://rtd-redirects-test.readthedocs.io/en/latest/additional works as expected
• https://rtd-redirects-test.readthedocs.io/en/latest/additional/ (with a trailing slash) yields a 404
• https://rtd-redirects-test.readthedocs.io/en/latest/current/ (with trailing slash) works as expected
• https://rtd-redirects-test.readthedocs.io/en/latest/current (no trailing slash) yields a 404

IOW, with the dirhtml builder of Sphinx, every moved page needs two redirects — one with trailing slash and one without.

Hi, we are in the process of re-working our redirects feature. This use case will be solved with #10881.
