Could you give some explanations wrt. your RewriteCond ? I have never seen this kind of expressions before.
Yes. \1 is a regEx internal back reference containing everything matched in the first group (/test/.+)So assuming a request of /test/index.html (=value of $1) from http://example.com/test/index.html (referer), the TestString
(left) is http://example.com/test/index.html<>/test/index.htmlThe regEx '(/test/.+)<' would match '/test/index.html<' and capture the part '/test/index.html' in a back reference. Now the pattern matches the > from the TestString followed by the value of the first back reference from within that regEx, which is '/test/index.html'.
So http://example.com/test/index.html<>/test/index.html (testString) would match against the pattern /test/index.html<>/test/index.html, the RegEx-Engine returns true. The result is now negated in mod_rewrite by the exclamation mark resulting in false which would abort this RewriteRule.
RewriteEngine On RewriteCond %{HTTP_REFERRER}<>$1 !(/test/.+)<>\1$ RewriteRule ^(/test/[^/]*\.(html?|php))$ /test-redir.php?page=$1 [L,NS]
