# Custom 404 page
ErrorDocument 404 "/log4j/2.x/404.html"

# Rewrite rules
RewriteEngine On
RewriteBase "/log4j/2.x/"

##
# To simplify the redirection rules, we normalized them:
#
# 1. If the request URIs ends in `/` (necessarily a `path-info`), we add `index.html` to it:
RewriteRule "^(.*)/$" "$1/index.html" [DPI]
# 2. If the request URI points to a (non-existent) file, we try adding `.html`:
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond $1 "!\.html$"
RewriteRule "^(.+)$" "$1.html"
#
# From this point rules match against the URI to the real file, with "/log4j/2.x/" stripped.

# The content moved between pages

# These redirects are special, since:
#
# 1. `mod_negotiate` is active and it is applied before `mod_rewrite`,
# 2. we replaced a directory like `log4j-api/` with a file that has the same prefix like `log4j-api.html`,
#
# if the URI path is `/log4j/2.x/log4j-api/foo` we must match `log4j-api.html/foo`.
