How to embed absolute links when serving from a subdirectory in a domain?

[schungx]

Say, I have a link going to another page and I need it starting from the root:

[some url link](/path/to/page.md)

This gets compiled to a link to the correct page:

<a href="/path/to/page.html">some url link</a>

However, this doesn't work if I'm serving from a subdirectory:

http://example.com/my_book/path/to/page.html

The absolute url will skip over the subdirectory my_book and point to http://example.com/path/to/page.html which doesn't exist.

How can we specify that links should go to an absolute path based upon the root location of the book?

Right now, I solved it by using https://github.com/avitex/mdbook-tera which is a pre-processor.

I added a variable in front of every URL link. The variable maps to the subdirectory name.

I am hoping for a simpler, not so hacky solution though.

@schungx Would you mind sharing exactly how you solved it in this way?
