copied!<p>You seem to have misunderstood what the rewrite module (and your rules specifically) actually does.</p> <p>Quite simply when you browse to:</p> <pre><code> localhost/abc/product.php?id=23 </code></pre> <p>The RewriteRule isn't invoked and shouldn't be doing anything. There's nothing wrong here, you're just browsing to the <strong>wrong</strong> URL</p> <h2>URL Transformation</h2> <pre><code>http://www.yoursite.com/product/123 <- URL that user goes to http://www.yoursite.com/product.php?id=123 <- Rewritten URL that the server sees </code></pre> <h2>RewriteRule(s) explanined</h2> <p>A rewrite rule is broken down into <em>three</em> parts (not including the <code>RewriteRule</code> part...)</p> <ol> <li>The regex that it matches against the url</li> <li>The url that it transforms into</li> <li>Additional options</li> </ol> <p>Given your rule:</p> <pre><code>RewriteRule ^product/([^/.]+)/?$ product.php?id=$1 [L] </code></pre> <p>The regex is: <code>^product/([^/.]+)/?$</code><br> The new url : <code>product.php?id=$1</code><br> The options : <code>[L]</code></p> <p>This means that the user browses to the <em>nice</em> url <code>http://www.yoursite.com/product/123</code> (and all of your links point to the <em>nice</em> URLs) and then the server matches against the regex and transforms it to the new URL that <strong>only the server sees</strong>.</p> <p>Effectively, this means that you have two URLs pointing to the same page... The <em>nice</em> URL and the <em>not-nice</em> URL both of which will take you to the same place. The difference is that the <em>not-nice</em> / <em>standard</em> URL is hidden from the general public and others pursuing your site.</p> <hr> <h2>Regex</h2> <p>The reason why <code>http://mysite.com/product/image.jpg</code> is not being redirected is because of the regex that you use in your <code>RewriteRule</code>.</p> <h3>Explanation</h3> <pre><code>^product/([^/.]+)/?$ </code></pre> <ul> <li><code>^</code> => Start of string</li> <li><code>product/</code> => Matches the literal string <code>product/</code></li> <li><code>([^/.]+)</code> => A capture group matching <em>one or more</em> characters up until the next <code>/</code> or <code>.</code></li> <li><code>/?$</code> => Matches an optional <code>/</code> followed by the end of the string</li> </ul> <p>Given the URL:</p> <pre><code>http://mysite.com/product/image.jpg </code></pre> <p>Your regex matches <code>product/image</code> but then it encounters <code>.</code> which stops the matching... As that isn't the end of string <code>$</code> the rule is invalidated and thus the transform never happens.</p> <p>You can fix this by changing your character class <code>[^/.]</code> to just <code>[^/]</code> or - my <em>preferred</em> method - to remove the character class and simply use <code>.+</code> (seeing as your capturing everything to the end of the string anyway</p> <pre><code>RewriteRule ^product/([^/]+)/?$ product.php?id=$1 [L] RewriteRule ^product/(.+)/?$ product.php?id=$1 [L] </code></pre>
