Subject Re: [users@httpd] RewriteRule: Pattern matching and grouping part of the URL expands to its local filesystem path

I'd suggest to try Redirect or RedirectMatch for these use cases, they are
less complicated and more straightforward:

https://httpd.apache.org/docs/2.4/mod/mod_alias.html#redirect

As you can see in https://httpd.apache.org/docs/current/mod/core.html#if
the <If> block accepts only directives that are usable in the directory
context (
https://httpd.apache.org/docs/current/mod/directive-dict.html#Context), and
this is a special note in the RewriteRule docs that might clarify what's
happening:

"In per-directory context (Directory and .htaccess), the Pattern is matched
against only a partial path, for example a request of "/app1/index.html"
may result in comparison against "app1/index.html" or "index.html"
depending on where the RewriteRule is defined."

If I am right a note in the docs might clarify any doubts like yours, but
need to double check first :)

Luca
