Configure HTTP

	Concepts		Procedures		More Information

The Configure HTTP page configures the filer for HTTP service. 

If you purchased HTTP when you purchased the filer, you already set up some of the configuration parameters for HTTP when you used setup to initialize the filer.

If you did not purchase HTTP when you purchased the filer, you need to purchase a new HTTP license to set up HTTP on the filer.

Configuration fields

There are several fields that can be configured when setting up HTTP.

Warning: If you disable HTTP (by setting the HTTP Administration or HTTP Enabled field to No), FilerView will no longer be accessible after you click Apply.

The following is a list of those fields and their descriptions.

• HTTP:

  The filer requires a software license to enable HTTP service. The license is installed on the filer at the factory per your order, so the initial setup of your filer does not involve entering a license code.

  You need to enter a license code only if any of the following conditions applies:

  You purchased a filer with a version of Data ONTAP earlier than Data ONTAP 4.0 and you just upgraded it to the current version.

  You want to enable a protocol not previously licensed for your filer.

  You just reinstalled the filer's file system.

  Network Appliance provides you with the appropriate license codes when shipping you the software upgrade kit or when giving you instructions for obtaining the software upgrade over the Internet.

• HTTP Enabled:

  Warning: If you disable HTTP (by setting the HTTP Administration field to No), FilerView will no longer be accessible after you click Apply.

  Stops or starts HTTP service immediately.

• HTTP Administration:

  Warning: If you disable HTTP (by setting the HTTP Administration field to No), FilerView will no longer be accessible after you click Apply.

  Provides or prevents access to the filer's online Help files and other files used by FilerView.

  Yes enables access to these files.

  No prevents access to FilerView and to the filer's online Help files.

• HTTP Root Directory:

  Specifies the root directory that contains the files and directories to be read by HTTP clients. 

  When a user enters a URL on the filer, the path component of the URL is a path name relative to the HTTP root directory.

  Enter the complete path name, such as /vol/vol0/home/users/pages.

• HTTP Timewait Enabled:

  When enabled, the filer puts HTTP connections that were closed by the client into the TIME_WAIT state for one minute, which is twice the maximum segment lifetime. 

  By default, HTTP timewait is disabled and the TIME_WAIT state is bypassed for HTTP connections.

• Request Timeout:

  Specifies the minimum amount of time, in seconds, before an idle HTTP connection times out.

• Maximum Log File Size:

  Specifies the size of the /etc/log/httpd.log file to a value other than the default of 2147483647 bytes (2 GB minus 1 byte).

Cluster considerations

In a cluster, either both filers or neither must be licensed for HTTP for takeover to occur properly.

The HTTP Timewait Enabled field and the Request Timeout field must each have the same value on both filers in a cluster for takeover to occur properly.
