    • Clustering reverse proxies

      17
      • 1. The client sends an HTTP request that includes an XML.load call to the origin server:

        17
      • 2. The load balancer on the remote network intercepts the request and routes it to one of the edge servers in the cluster.

        17
      • 3. This edge server then acts as an FPAD client and broadcasts an FPAD message.

        17
      • 4. The edge servers enrolled in the cluster respond with their affinity values.

        17
      • 5. The broadcasting edge server chooses the edge server with the lowest affinity value.

        17
      • 6. This edge server sends the required information back to the client:

        17
      • 7. The client then uses the information to make an explicit connection: first to the edge, then to the origin server using a wrapped URI:

        18
    • Setting up origin and proxy servers

      18
      • To set up a cluster of edge servers:

        19
        • 1. Install and configure the first Flash Media Server.

          19
        • 2. Confirm that this Flash Media Server instance is working correctly.

          19
        • 3. Configure the Flash Media Server instance as an origin server.

          19
        • 4. Install and configure the next Flash Media Server in the cluster.

          19
        • 5. Configure this Flash Media Server instance as an edge server.

          19
        • 6. Make sure this edge server points to the origin server.

          19
        • 7. Repeat steps 5 through 7 for each edge server that your license file allows.

          19
  • Maintaining edge server clusters

    19
    • Clearing the edge server cache

      20
      • To create a scheduled cache clearance:

        20
        • 1. Create a cache.bat file to empty the cache directory.

          20
        • 2. Run the cache.bat file and verify that it deletes files in the cache directory.

          20
        • 3. Select Control Panel > Scheduled Tasks > Add Scheduled Task.

          20
        • 4. Select cache.bat as the new file to run.
