'RewriteRule in folder breaks parent (.htaccess)

# /.htaccess
RewriteEngine on
RewriteBase /
RewriteRule "^([^/]+)/root/(.*)"   "$1/index.php?root=$2"

# /folder/.htaccess
RewriteRule "^sub/(.*)"            "index.php?sub=$1"

Each folder's RewriteRule works in isolation:

  • /folder/root/hi => /folder/index.php?root=hi
  • /folder/sub/hello => /folder/index.php?sub=hello

Q: Why does adding any RewriteRule in the subfolder (/folder/.htacces) break the one in the web root (causes 404)? What do I need to do to create rules on different levels?

I've tried adding RewriteOptions Inherit(Down), but that didn't have any effect.

You need to change your root .htaccess rule to this:

RewriteRule ^([^/]+/)?root/(.*)$ $1index.php?root=$2 [L,QSA]

This is to make initial part [^/]+/ an optional match in order to make same rule work from root .htaccess as well as from a /folder/.htaccess.

Then have this in your folder/.htaccess:

RewriteOptions Inherit
RewriteEngine On

RewriteRule ^sub/(.*)$ index.php?sub=$1 [L,QSA]

RewriteOptions Inherit will inherit all rules and directives from parent .htaccess and will apply them in child's context after applying all the rules defined in child .htaccess.

With Apache 2.4, I've success by adding RewriteOptions InheritDownBefore in the parent .htaccess.
