Workaround required for apache URL bug

This is a bit of a hack, but it's pretty clean. Add this to the (virtual) server container in the Apache config:

# Catch pesky %2f Apache bug 'not founds'
ErrorDocument 404 /index.php

Disadvantages:

1. This change is not possible for users on shared hosts
2. It doesn't work for alternative front controllers (eg if index.php is specified in this workaround, then using frontend_dev.php with a URL containing %2f will result in a 404 within symfony.

I have fixed issue 2 above. Replace the virtual server container directive above with this:

# Catch pesky %2f Apache bug 'not founds'
ErrorDocument 404 /error_handler.php

And then create "error_handler.php" in your web folder:

<?php
define('DEV_FRONT_CONTROLLER', 'frontend_dev.php');
define('DEV_FRONT_CONTROLLER_URI', '/' . DEV_FRONT_CONTROLLER);
define('PROD_FRONT_CONTROLLER', 'index.php');
define('PROD_FRONT_CONTROLLER_URI', '/' . PROD_FRONT_CONTROLLER);

// Hack the front controller name for the benefit of the routing module
$_SERVER['SCRIPT_NAME'] = DEV_FRONT_CONTROLLER_URI;

// Switch to the appropriate front controller
$uri = $_SERVER['REQUEST_URI'];
if (substr($uri, 0, strlen(DEV_FRONT_CONTROLLER_URI)) == DEV_FRONT_CONTROLLER_URI)
{
  require DEV_FRONT_CONTROLLER;
}
else
{
  require PROD_FRONT_CONTROLLER;
}

I haven't worked out how to fix issue 1 in a shared Apache environment, other than avoiding %2f, or urlencoding/decoding twice, which is a pain.

Hmm, the above strangely works but, for correctness, it should be:

<?php
define('DEV_FRONT_CONTROLLER', 'frontend_dev.php');
define('DEV_FRONT_CONTROLLER_URI', '/' . DEV_FRONT_CONTROLLER);
define('PROD_FRONT_CONTROLLER', 'index.php');
define('PROD_FRONT_CONTROLLER_URI', '/' . PROD_FRONT_CONTROLLER);

// Switch to the appropriate front controller
$uri = $_SERVER['REQUEST_URI'];
if (substr($uri, 0, strlen(DEV_FRONT_CONTROLLER_URI)) == DEV_FRONT_CONTROLLER_URI)
{
  $_SERVER['SCRIPT_NAME'] = DEV_FRONT_CONTROLLER_URI;
  require DEV_FRONT_CONTROLLER;
}
else
{
  $_SERVER['SCRIPT_NAME'] = PROD_FRONT_CONTROLLER_URI;
  require PROD_FRONT_CONTROLLER;
}

This should be moved to dev mailing list..

You can use the Apache AllowEncodedSlashes directive and set it to on to accept %2F
