## General Information

The web_concurrent_end function marks the end of a concurrent group and initiates the concurrent execution of all the functions that were registered as concurrent—those between the web_concurrent_start and web_concurrent_end functions. Click Concurrent Groups for a list of functions that may be included within a concurrent group.

Note that the functions included within the concurrent group are not executed immediately. Instead they are registered for concurrent execution. When the concurrent group is closed, all of the functions registered as concurrent are executed together. The number of items submitted in parallel depends on the browser being emulated.

This function is supported for all web scripts.
