A number of ABCUpload settings can be overridden using settings in the registry. If you are not familiar with the precautions you should take when using RegEdit we suggest you do not change these settings.

All ABCUpload keys are stored under the following Registry Path.

HKEY_LOCAL_MACHINE\SOFTWARE\WebSupergoo\ABCUpload\4.0

If LogErrors is set to 1 then all VBScript errors raised will also be put into the Application Event Log.

The AutoRecover key determines what happens if a potentially fatal error is caught. By default we automatically recover if running on Windows NT 4.0 since the alternative is to stop the entire web server. On Windows 2000 we stop the web server because we know that Reliable Restart will handle the problem. You can override this behavior by altering the AutoRecover key. Setting it to 1 will always attempt to automatically recover. Whatever action is taken an error will be logged in the Application Event Log.

We consider impersonation such a security risk that we ship ABCUpload with impersonation disabled. If you wish to enable it you must do so via the EnableImpersonation registry key. This should be set to 1.

The ReadChunkSize determines how much upload data is read at one time. It effectively determines the granularity of the progress bar. Smaller values allow greater precision in keeping track of progress but place a greater overhead on the server. The default value is 2048 (0x0800) bytes which means that the progress bar will increment in chunks 2 KB in size.
