To Create a Protocol

  1. In the navigation tree, expand the Configuration node.
  2. Under the Configuration node, expand the Network Config node.
  3. Under the Configuration node, select the Protocols node.

    The Protocols page opens.

  4. On the Protocols page, click New.

    The New Protocol page opens.

  5. On the New Protocol page, in the Name field, type the name of the protocol.
  6. Select the Security Enabled checkbox to enable security for the protocol.
  7. Select the Comet Support Enabled checkbox to enable Comet support for the protocol.
  8. In the Max Connections field, type the maximum number of persistent connections to be maintained in Keep-Alive mode.

    The Keep-Alive subsystem periodically polls idle connections.

  9. From the Default Virtual Server drop-down list, select the virtual server to be associated with the protocol.

    Use the Virtual Servers page to define virtual servers.

  10. In the Server Name field, type the host name to be used in the URLs the server sends to the client.

    This name is the alias name if your server uses an alias. If your server does not use an alias, leave this field blank.

  11. In the Redirect Port field, type the port value to be used to redirect a request to another port.

    The Enterprise Server automatically redirects the request if these two conditions exist:

    If a redirect port is not specified, the Enterprise Server uses the port number specified in the original request.

  12. Select the Status Enabled checkbox to enable the file cache.

    This option is selected by default.

  13. In the Max Age field, type the maximum age, in seconds, for a valid cache entry.

    This parameter controls how long cached information is used after a file has been cached. An entry older than the maximum age is replaced by a new entry for the same file. If your content changes infrequently, increase this value for improved performance.

    The optimum maximum age depends on whether existing files are modified regularly. For example, if files are modified four times a day at regular intervals, consider setting the maximum age to 21600 seconds (6 hours). Otherwise, consider setting the maximum age to the longest time for which you are willing to serve the previous version of a file after the file has been modified.

    The default value is 30.

  14. In the Max Cache Size field, type The maximum total size (in bytes) of the file cache on disk.

    The default value is 10485760.

  15. In the Max File Count field, type the maximum number of files that can be stored in the file cache.

    If the value is too big, the server caches little-needed files, which wastes memory. If the value is too small, the benefit of caching is lost. Try different values of this attribute to find the optimal solution for specific applications.

    The default value is 1024.
