Baloney, MTDLL = multi-threaded dll. It helps with scaling. And yes it really scales. You can even call an asynchronous web job that is an actual thread to run in the background. You really have been out of vfp a while, haven't you?? Maybe you should read Calvin's classic paper which explains VFP's multi-threading in detail.
>>Aren't you misunderstanding the issue here? It is the web server (whether it be Apache or IIS) that launches the thread and in the case of PHP the thread is irrelevant. The problems arise when any components used to handle the thread request are not themselves threadsafe. In the case of a VFP COM component I don't think you can do achieve that without instantiating a separate instance of the runtimes for each thread. That doesn't scale well.....
