cflock timeout

[Hal B. Helms]

The timeout property sets the amount of time a session variable will be active. Note that while you can make it shorter than the default timeout set in the CF Administrator, you cannot make it longer.

[BKBK]

A session lock and its attributes apply to each individual session
on its own, without any direct inter-session interactions.
When the processing flow for a session reaches a session lock,
the timeout is the maximum number of seconds that it may
wait to obtain the lock. That is, how long it may wait to get
the okay-flag to run the code within the cflock tag. If the
lock is obtained within the timeout period, execution continues
normally.

If the lock is not obtained within the timeout period, further
code execution depends on whether the ThrowOnTimeout
attribute is set to "Yes" or "No". If "Yes", Coldfusion throws
an error and code execution stops. If "No", the processing
flow continues beyond the cflock tag, without executing the
code within the tag.

Coldfusion's behaviour is a bit peculiarity, when you set the
timeout value to "0". Then the timeout value actually defaults
to the value T, where T comes from the "Timeout Requests after T"
setting in the ColdFusion Administrator. This assumes that that
setting is enabled. If it is not, and you set timeout="0" in a
cflock tag, ColdFusion might wait for an indefinite amount of
time to obtain the lock.
