|
|

* (root)/../_ss_environment.php, or (root)/../../_ss_environment.php
|
2008-02-25 03:10:37 +01:00

|
* - Sets up error handlers with {@link Debug::loadErrorHandlers()}
|
2008-08-11 01:29:30 +02:00
|
|
|
* - Calls {@link DB::connect()}, passing it the global variable $databaseConfig that should
|
2009-03-22 23:59:14 +01:00
|
|
|
* be defined in an _config.php
|
2008-02-25 03:10:37 +01:00

* - Sets up the default director rules using {@link Director::addRules()}
|
|
|
|
*
|
2008-08-11 01:29:30 +02:00
|

|

|
* real work.

* To use SilverStripe, every request that doesn't point directly to a file should be rewritten to
|
|
|
|
* framework/main.php?url=(url). For example, http://www.example.com/about-us/rss would be rewritten
|
|
|
|
* to http://www.example.com/framework/main.php?url=about-us/rss

2008-08-11 01:29:30 +02:00
|
|
|
* It's important that requests that point directly to a file aren't rewritten; otherwise, visitors
|
|
|
|
* won't be able to download any CSS, JS, image files, or other downloads.
