Checkpoints

Enables logging checkpoint events. Checkpoint events log bytes periodically from the start to the end of an event. The 
following are available as checkpoint events: 

connect-continue

, 

play-continue

, and 

publish-continue

. 

This element contains the enable attribute which you can set to 

true

 or 

false

. Set the 

enable

 attribute to 

true

 to 

turn on checkpoint events in logs. The default value is 

false

.

You must enable checkpoint events at the server level in the Server.xml file. You can disable checkpoints at the vhost 
and application level in the Vhost.xml and Application.xml files. You can also override the logging interval at the vhost 
and application levels.

Contained elements

CheckInterval

, 

LogInterval

ConnectionTimeout

Flash Media Server 4.5

The 

/RTMP/ConnectionTimeout

 element and 

/HTTP/ConnectionTimeout

 element specify how long to wait before 

timing out an outgoing connection, in milliseconds. The default is -1 which uses the OS timeout to block outgoing 
connections.

<ConnectionTimeout>-1</ConnectionTimeout>

Connector

Container element.

The elements nested within the 

Connector

 container configure the connector subsystem. Flash Media Server provides 

connectors that allow application scripts to connect to other Flash Media Servers or HTTP servers.

Contained elements

HTTP

, 

RTMP (Connector)

Content

Enables operations in the current File plug-in on content (streams or SWF files). The value of 

true

 enables the 

operation on the specified content type and 

false

 disables it. 

This element contains the 

type

 attribute, which you can set to the following values:

•

Streams

. Enables stream file operations. Enabled by default.

•

SWF

. Enables operations on SWF files. Disabled by default. Enable if you plan to use the File plug-in to retrieve SWF 

files for verification by the server.

This element is nested within the 

FilePlugin

 tag.
