Contao 3 Module: Proxy
|
||||
======================
|
||||
|
||||
Offline Fork from the old TYPOlight Module „Proxy“.
|
||||
|
||||
Description
|
||||
-----------
|
||||
|
||||
No official transfer! I have changed the Module for using with Contao 3.0.
|
||||
|
||||
### Installation
|
||||
|
||||
- Download the ZIP file
|
||||
- unpack on your hard drive
|
||||
- on the server in the directory `system/modules` , create a new directory `proxy`
|
||||
- copy into the directory `system/modules/proxy` then the files and directories
|
||||
|
||||
So then there must exist:
|
||||
|
||||
- `system/modules/proxy/classes/Proxy.php`
|
||||
- `system/modules/proxy/config/autoload.php`
|
||||
etc.
|
||||
|
||||
### Using
|
||||
|
||||
In the backend, in System - Settings, there is now the new section "Proxy Settings". When the extension catalog and installation works, the
|
||||
module should be installed again over the extension catalog. So updates are displayed in the extension manager, if there is one.
|
||||
|
||||
|
||||
Beschreibung
|
||||
------------
|
||||
|
||||
Keine offizielle Übernahme! Ich habe das Modul für Contao 3.0 angepasst, um weiter damit arbeiten zu können.
|
||||
|
||||
### Installation
|
||||
|
||||
- Download ZIP Datei, oben auf dieser Seite ist dazu der Link zu finden
|
||||
- auf lokaler Festplatte auspacken
|
||||
- auf dem Server im Verzeichnis `system/modules` ein neues Verzeichnis `proxy` anlegen
|
||||
- in das Verzeichnis `system/modules/proxy` nun die Dateien und Verzeichnisse übertragen
|
||||
|
||||
Es muss also damit existieren:
|
||||
|
||||
- `system/modules/proxy/classes/Proxy.php`
|
||||
- `system/modules/proxy/config/autoload.php`
|
||||
usw.
|
||||
|
||||
### Nutzung
|
||||
|
||||
Im Backend unter System - Einstellungen ist der Abschnitt "Proxy-Einstellungen" zu finden.
|
||||
|
||||
Sobald damit der Erweiterungskatalog und die Installation funktioniert, sollte das Modul Proxy nochmal über den Erweiterungskatalog installiert
|
||||
werden. Damit werden Updates in der Verwaltung angezeigt, sofern welche vorhanden sind.
