I have IIS dynamic compression turned on for JSON and XML mime types. I have noticed that when IE receives an AJAX callback with compressed results, the UI process will completely halt while IE decompresses the result. In other words, the entire browser UI appears to lock up for the duration of the decompression.
Is there a workaround for this behavior? Why in the world would IE be decompressing callbacks in the same thread as the UI?
Thanks - all suggestions and insight appreciated.
