/** |

|
* Router. |
32
|
|
|
* |
33
|
|
|
* Router does URL Formatting and internal Rewriting. |
34
|
|
|
* The URL is segmented and restructured to fit the internal route to a controller. |
35
|
|
|
* The internal routes are described in a central routing configuration file. |
36
|
|
|
* This central config is updated on installation and deinstallation of modules and plugins. |
37
|
|
|
* |
38
|
|
|
* @see \Koch\Routes\Manager |
39
|
|
|
* |
40
|
|
|
* Normally all requests made map to a specific physical resource rather than a logical name. |
41
|
|
|
* With Routing you are able to map a logical name to a specific physical name. |
42
|
|
|
* Examples: map a logical URL (a mod_rewritten one) to a Controller/Method/Parameter |
43
|
|
|
* or map a FileRequest via logical URL (a mod_rewritten one) to a DownloadController/Method/Parameters. |
44
|
|
|
* Routes are a valuable concept because they separate your URLs from your data. |
45
|
|
|
* |
46
|
|
|
* There are two different URL Formatings allowed: |
47
|
|
|
* 1. Slashes as Segment Dividers-Style, like so: /mod/sub/action/id |
48
|
|
|
* 2. Fake HTML File Request or SMF-Style, like so: /mod.sub.action.id.html |
