[This is preliminary documentation and subject to change]
IIS performs on-demand compression of static content in the background. When a static file is requested, and IIS has determined that a previously compressed version of the requested file does not already exist in the compression directory, the request is put into a simple FIFO (first in, first out) queue. HcMaxQueueLength specifies how many concurrent background compression requests can be in the queue. If the queue is full, additional compression requests are ignored until there is room in the queue.
If HcMaxQueueLength is set to 0xFFFFFFFF, there is no limit to the number of pending requests in the queue.
