What is matched?5\nIn VirtualHost context, The Pattern will initially be matched against the part of the URL after the hostname and port, and before the query string (e.g. \u201c/app1/index.html \u201d).\nIn Directory and htaccess context, the Pattern will initially be matched against the filesystem path, after removing the prefix that led the server to the current RewriteRule (e.g. \u201c app1/index.html \u201d or \u201c index.html \u201d depending on where the directives are defined).\nIf you wish to match against the hostname, port, or query string, use a RewriteCond with the %{HTTP_HOST}, %{SERVER_PORT}, or %{QUERY_STRING} variables respectively.\nIn any case, remember that regular expressions are substring matches. That is, you don \u2019 t need the regex to describe the entire string, just the part that you wish to match. Thus, using a regex of . is often sufficient rather than .*, and the regex abc is not the same as ^abc$.
