Edit Protocol

Use the Edit Protocol page to modify an existing protocol.

The Edit Protocol, HTTP, and File Cache pages contain the following options.

Name

The name of the protocol. The Name field is a read-only field. You can only specify the Name when you create a new protocol

Security

If this option is selected, security is enabled for the protocol.

Comet Support

If this option is selected, Comet support is enabled for the protocol.

Max Connections

The maximum number of persistent connections to be maintained in Keep-Alive mode. The Keep-Alive subsystem periodically polls idle connections. The default value is 256.

Default Virtual Server

The virtual server to be associated with the protocol. Use the Virtual Servers page to define virtual servers.

Server Name

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.

Redirect Port

Port value that redirects 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.

Status

If this option is selected, the file cache status is enabled. This option is selected by default.

Max Age

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.

Max Cache Size

The maximum total size (in bytes) of the file cache on disk. The default value is 10485760.

Max File Count

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.
