You can specify the number of simultaneous requests that can be processed for each of the following types of requests:
CFM page requests
CFC method invocations (via an HTTP GET)
Flash Remoting requests
Web Service requests
The settings are contained completely within ColdFusion code and work across all J2EE application servers. You do not have to restart the ColdFusion server for changes to the configuration to take effect. JSP processing is not affected by these changes.
Note: The Flash Remoting request control setting applies to remoting that uses ActionScript 2.0 and ActionScript 3.0, with each type treated independently. For example, a setting of 5 means that up to 5 ActionScript 2.0 Flash Remoting and 5 ActionScript 3.0 Flash Remoting requests are allowed simultaneously.
Capabilities by edition
Standard Edition: Only the Async CFML, DirectoryWatcher, Socket, and user written event gateways are enabled. The maximum number of threads in the pool for the cfthread tag is limited to 10. Only the CFM page request limit is adjustable; this changes the activeHandlerThreads in JRun, exactly like ColdFusion 7.
Enterprise Edition: All event gateways are supported. The number of threads in the pool for the cfthread tag is unlimited. You can adjust the limits for each request type (CFM page, CFC, Flash Remoting, and Web Service) independently.
