Register Request Handlers

Any request handlers you create must be registered in the RequestHandlerFactory in order to work. The built-in request handlers are registered as follows:

requestHandler.0003=./TwitterRequestHandler
requestHandler.0004=./YoutubeRequestHandler
requestHandler.0005=./InstagramRequestHandler
requestHandler.0006=./VineRequestHandler
requestHandler.0007=./VimeoRequestHandler

The numbers in the property names determine the order in which provider host names are matched.

To add your own request handlers:

Create a RequestHandlerFactory.properties file in your webapp configuration layer as follows:

$touch /etc/escenic/engine/common/com/escenic/livecenter/service/proxy/RequestHandlerFactory.properties

Open the file for editing and add properties to register your request handlers, using different number suffixes from the built-in request handlers. For example:
```
requestHandler.0008=./FlickrRequestHandler
requestHandler.0009=./CNNRequestHandler
```
If you actually want to override one of the supplied request handlers with your own, you can do so by simply redefining the appropriate property. You can, for example, replace the supplied TwitterRequestHandler with your own custom implementation by entering something like:
```
requestHandler.0003=./CustomTwitterRequestHandler
```
