# Short links for URLs in the book ## Problem: link rot _Fluent Python, Second Edition_ has more than 1000 links to external resources. Inevitably, some of those links will rot as time passes. But I can't change the URLs in the print book... ## Solution: indirection I replaced almost all URLs in the book with shortened versions that go through the `fpy.li` site which I control. The site has an `.htaccess` file with *temporary* redirects. When I find out a link is stale, I can thange the redirect in `.htaccess` to a new target, so the link in the book is back in service through the updated redirect. ## Help wanted Please report broken links as bugs in the [`FPY.LI.htaccess`](FPY.LI.htaccess) file. Also, feel free to send pull requests with fixes to that file. When I accept a PR, I will redeploy it to `fpy.li/.htaccess`. ## Details Almost all URLs in the book are replaced with shortened versions like [`http://fpy.li/1-3`](http://fpy.li/1-3)—for chapter 1, link #3. There are also custom short URLs like [`https://fpy.li/code`](https://fpy.li/code) which redirects to the example code repository. I used custom short URLs for URLs with 3 or more mentions, or links to PEPs. Exceptions: - URLs with `oreilly` in them are unchanged; - `fluentpython.com` URL (with no path) is unchanged; The `FPY.LI.htaccess` is deployed at the root folder in `http://fpy.li`.
