We have an application with OpenLayers 2. There we are using WMS layers, which make requests to an custom Web service. This Web service creates an image for the current map window. To achieve that, we use the getUrl method, where the bounds are passed and where we build the URL for the request.
For OpenLayers 3 I have not seen that possibility. What is the best way here to solve this?
EDIT: In ol2, we used the getUrl method of the WMS layer object to build a specific url for each WMS request. Is there an equivalent there for ol3?
