154 Configuration Files

HttpUserInfo

This tag specifies the physical location where the user-defined XML file is stored in the server.

Description

By default the XML files are placed in the uInfo directory in the server installation directory.

When the

enable attribute is set to “true”, Flash Media Server responds to the HTTP

request and returns the content of the XML file in the

uInfo directory. The default setting for

the

enable attribute is “false”.

Users can specify any XML file in the

uInfo folder. The uInfo folder is configured to point to

C:\fms\uInfo.

To get the XML file from the server, the HTTP request must begin with:

http://server:port/fms/uInfo

The syntax for an HTTP request for an XML file in C:\fms\uInfo\foo\bar.xml is:

http://server:1935/fms/uInfo/foo/bar.xml

IdleAckInterval

This tag specifies the maximum time the server may wait before it sends back an ack

(acknowledgement code) for a client idle post.

Ack is shorthand for acknowledgement code, a transmission control character used to indicate

that a transmitted message was received uncorrupted or without errors. It also indicates that

the receiving server is ready to accept transmissions. The receiver sends the code to the sender

to indicate that the transmission has been accepted.

The values for this tag and the

IdlePostInterval tag affect the latency observed by a client

tunneling into the server. These tags should be configured at the same time.

Description

The default settings for the IdleAckInterval and IdlePostInterval tags provide medium

latency and is 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 the

IdlePostInterval and IdleAckInterval tags. Those applications not sensitive to high

latencies may use the combination 1024/2048.
