title: WSO2 API Manager redirect according to client
body: <p>Is it possible to have the API Manager redirect an incoming client API call to a back-end URL customized according to the client data?</p>
  
  <p>In our back-end we're activating different instance URLs for each client, e.g.:</p>
  
  <ul>
  <li>client1.api.domain.internal</li>
  <li>client2.api.domain.internal</li>
  <li>...</li>
  </ul>
  
  <p>Clients connect to the API Manager to a unique shared address, e.g. api.domain.ext, and then clients shall be routed to the internal API accordingly (the parameter is bound to the client profile).</p>
  
  <p>Is this achievable via configuration or is it necessary to develop a custom component?</p>
