# URL Variable Tools
|
|
|
|
## Introduction
|
|
|
|
This page lists a number of "page options" , "rendering tools" or "special URL variables" that you can use to debug your
|
|
SilverStruoe applications. These are consumed in PHP using the $_REQUEST or $_GET super globals throughout the SilverStripe
|
|
core.
|
|
|
|
**General Usage**
|
|
|
|
Append the option and corresponding value to your URL in your browser's address bar. You may find the [Firefox UrlParams extension](https://addons.mozilla.org/en-US/firefox/addon/1290) useful in order to debug a POST requests (Like Forms).
