    copied!<p>I have a CodeIgniter site which works fine locally, but now I've uploaded it to another server it breaks under a very specific condition.</p> <p>The server will drop the connection if I try and redirect to a URL that has a route in routes.php</p> <p>I.e.</p> <pre><code>$route['controller/dothis(:any)?'] = "controller/method/dothis$1"; $route['controller/dothat(:any)?'] = "controller/method/dothat$1"; </code></pre> <p>The server is running Apache, and there is no error in any of the logs, the server just drops the connection, and returns nothing to the client.</p> <p>The sequence of events is this:</p> <ol> <li>Pages loads fine</li> <li>user submits a form via POST</li> <li>The controller receives the POST request</li> <li>The controller calls redirect() to /controller/dothis/xxx</li> <li>The server drops the connection</li> </ol> <p>I'm stumped on this one, and have never seen this behaviour before.</p> <p><strong>Update:</strong></p> <p>The logs end like this:</p> <p>Access log</p> <pre><code>2.217.174.75 - - [13/Oct/2011:18:29:04 +0100] "GET /home/index/ HTTP/1.1" 200 7209 2.217.174.75 - - [13/Oct/2011:18:31:18 +0100] "POST /home/index/ HTTP/1.1" 302 68 </code></pre> <p>Rewrite log</p> <pre><code>2.217.174.75 - - [13/Oct/2011:18:31:18 +0100] [89.234.23.46/sid#2b5effefb0f0][rid#2b5ef2745340/initial/redir#1] (3) [perdir /var/www/staging/html/] applying pattern '^(.*)$' to uri 'index.php' 2.217.174.75 - - [13/Oct/2011:18:31:18 +0100] [89.234.23.46/sid#2b5effefb0f0][rid#2b5ef2745340/initial/redir#1] (1) [perdir /var/www/staging/html/] pass through /var/www/staging/html/index.php </code></pre> <p>No entries in the PHP or Apache error logs.</p> <p>As you can see, the form is submitted, a redirect is attempted (status 302) then the connection just goes away on the browser end.</p> <p>There are no entries in syslog of Apache crashing.</p>
