| <p>This example uses an often-overlooked feature of mod_rewrite, |
| by taking advantage of the order of execution of the ruleset. In |
| particular, mod_rewrite evaluates the left-hand-side of the |
| RewriteRule before it evaluates the RewriteCond directives. |
| Consequently, $1 is already defined by the time the RewriteCond |
| directives are evaluated. This allows us to test for the existence |
| of the original (<code>document.html</code>) and target |
| (<code>document.php</code>) files using the same base filename.</p> |
| |
| <p>This ruleset is designed to use in a per-directory context (In a |
| <Directory> block or in a .htaccess file), so that the |
| <code>-f</code> checks are looking at the correct directory path. |
| You may need to set a <code class="directive"><a href="../mod/mod_rewrite.html#rewritebase">RewriteBase</a></code> directive to specify the |
| directory base that you're working in.</p> |

| <dd>The goal of this rule is to force the use of a particular |
| hostname, in preference to other hostnames which may be used to |
| reach the same site. For example, if you wish to force the use |
| of <strong>www.example.com</strong> instead of |
| <strong>example.com</strong>, you might use a variant of the |
| following recipe.</dd> |
| |
| <dt>Solution:</dt> |
| |
| <dd> |
| |
| <p>The very best way to solve this doesn't involve mod_rewrite at all, |
| but rather uses the <code class="directive"><a href="../mod/mod_alias.html#redirect">Redirect</a></code> |
| directive placed in a virtual host for the non-canonical |
| hostname(s).</p> |
| |
| <pre class="prettyprint lang-config"><VirtualHost *:80> |
| ServerName undesired.example.com |
| ServerAlias example.com notthis.example.com |
| |
| Redirect "/" "http://www.example.com/" |
| </VirtualHost> |
| |
| <VirtualHost *:80> |
| ServerName www.example.com |
| </VirtualHost></pre> |
| |
| |
| <p>You can alternatively accomplish this using the |
| <code class="directive"><a href="../mod/core.html#if"><If></a></code> |
| directive: (<strong>2.4 and later</strong>)</p> |
| |
| <pre class="prettyprint lang-config"><If "%{HTTP_HOST} != 'www.example.com'"> |
| Redirect "/" "http://www.example.com/" |
| </If></pre> |
| |
| |
| <p>Or, for example, to redirect a portion of your site to HTTPS, you |
| might do the following:</p> |
| |
| <pre class="prettyprint lang-config"><If "%{SERVER_PROTOCOL} != 'HTTPS'"> |
| Redirect "/admin/" "https://www.example.com/admin/" |
| </If></pre> |
| |
| |
| <p>If, for whatever reason, you still want to use <code>mod_rewrite</code> |
| - if, for example, you need this to work with a larger set of RewriteRules - |
| you might use one of the recipes below.</p> |
| |
| <p>For sites running on a port other than 80:</p> |
| <pre class="prettyprint lang-config">RewriteCond "%{HTTP_HOST}" "!^www\.example\.com" [NC] |
| RewriteCond "%{HTTP_HOST}" "!^$" |
| RewriteCond "%{SERVER_PORT}" "!^80$" |
| RewriteRule "^/?(.*)" "http://www.example.com:%{SERVER_PORT}/$1" [L,R,NE]</pre> |
| |
| |
| <p>And for a site running on port 80</p> |
| <pre class="prettyprint lang-config">RewriteCond "%{HTTP_HOST}" "!^www\.example\.com" [NC] |
| RewriteCond "%{HTTP_HOST}" "!^$" |
| RewriteRule "^/?(.*)" "http://www.example.com/$1" [L,R,NE]</pre> |
| |
| |
| <p> |
| If you wanted to do this generically for all domain names - that |
| is, if you want to redirect <strong>example.com</strong> to |
| <strong>www.example.com</strong> for all possible values of |
| <strong>example.com</strong>, you could use the following |
| recipe:</p> |
| |
| <pre class="prettyprint lang-config">RewriteCond "%{HTTP_HOST}" "!^www\." [NC] |
| RewriteCond "%{HTTP_HOST}" "!^$" |
| RewriteRule "^/?(.*)" "http://www.%{HTTP_HOST}/$1" [L,R,NE]</pre> |
| |
| |
| <p>These rulesets will work either in your main server configuration |
| file, or in a <code>.htaccess</code> file placed in the <code class="directive"><a href="../mod/core.html#documentroot">DocumentRoot</a></code> of the server.</p> |

| <p>Usually the <code class="directive"><a href="../mod/core.html#documentroot">DocumentRoot</a></code> |

| |
| |
| <dl> |
| <dt>Description:</dt> |
| <dd>You want to capture a particular value from a query string |
| and either replace it or incorporate it into another component |
| of the URL.</dd> |
| |
| <dt>Solutions:</dt> |
| <dd> |
| <p> Many of the solutions in this section will all use the same condition, |
| which leaves the matched value in the %2 backreference. %1 is the beginining |
| of the query string (up to the key of intererest), and %3 is the remainder. This |
| condition is a bit complex for flexibility and to avoid double '&&' in the |
| substitutions.</p> |
| <ul> |
| <li>This solution removes the matching key and value: |
| |
| <pre class="prettyprint lang-config"># Remove mykey=??? |
| RewriteCond "%{QUERY_STRING}" "(.*(?:^|&))mykey=([^&]*)&?(.*)&?$" |
| RewriteRule "(.*)" "$1?%1%3"</pre> |
| |
| </li> |
| |
| <li>This solution uses the captured value in the URL subsitution, |
| discarding the rest of the original query by appending a '?': |
| |
| <pre class="prettyprint lang-config"># Copy from query string to PATH_INFO |
| RewriteCond "%{QUERY_STRING}" "(.*(?:^|&))mykey=([^&]*)&?(.*)&?$" |
| RewriteRule "(.*)" "$1/products/%2/?" [PT]</pre> |
| |
| </li> |
| |
| <li>This solution checks the captured value in a subsequent condition: |
| |
| <pre class="prettyprint lang-config"># Capture the value of mykey in the query string |
| RewriteCond "%{QUERY_STRING}" "(.*(?:^|&))mykey=([^&]*)&?(.*)&?$" |
| RewriteCond "%2" !=not-so-secret-value |
| RewriteRule "(.*)" "-" [F]</pre> |
| |
| </li> |
| |
| <li>This solution shows the reverse of the previous ones, copying |
| path components (perhaps PATH_INFO) from the URL into the query string. |
| <pre class="prettyprint lang-config"># The desired URL might be /products/kitchen-sink, and the script expects |
| # /path?products=kitchen-sink. |
| RewriteRule "^/?path/([^/]+)/([^/]+)" "/path?$1=$2" [PT]</pre> |
| |
| </li> |
| </ul> |
