no-issue
This issue only occurs when using custom redirects with a subdirectory
setup, and the path to be redirected from is expressed as a regex, and
the url that is being redirected to is not an external url.
The issue has a few components:
- Redirect paths as a regex generally use the ^ to ensure that they
match the beginning of the path.
- The path that the regex is matched against conditionally excludes the
subdirectory, specifically, the subdirectory is excluded for external
urls
These combined means you end up with a regex like /^\/custom-redirect/
and a path like /subdir/custom-redirect, these will not match/replace
correctly, and you'll end in an infinite redirect loop.
The fix here is to *always* remove the subdirectory when testing regex's
and then conditionally adding it back *only* for the redirect, and only
if it is an internal redirect
