IdlePostInterval
This tag specifies in milliseconds the interval at which the client sends idle posts to the server
to indicate that Flash Player has no data to send.
Description
The default settings for the
IdleAckInterval
and
IdlePostInterval
tags provide medium
latency and are set to 512/512 milliseconds.
Low values reduce the latency but increase the network bandwidth overhead. Applications
desiring low latency may configure the combination of values 128/256 for
IdlePostInterval
and
IdleAckInterval
tags. Those applications not liable to high
latencies can use the configuration 1024/2048.

MaxFailures
This tag specifies the maximum number of failures an edge server may incur before it restarts.
Description
Default number of failures is 2.
MaxSize
This tag specifies the maximum number of XML files cached in the server.
Description
When the results from an HTTP request arrives from the origin server, the edge server loads
the XML files into a cache. If another client requests the same file, the edge server sends it
directly from the cache.
The default number of files in the cache is 100. Once the cache reaches the maximum size,
the server checks for and removes the least-used 30% of the cache.
MaxWriteDelay
The HTTP tunneling protocol ensures that a server will be able to write every four seconds.
Occasionally, when connections close under abnormal conditions the notification may not
reach the server, which may continue to place writes in a queue.
