Summary NPAPI routine NPN_RequestRead is not implemented

We are developing a plug-in to display structured (rather than streamed) documents from the web. Some of them are quite large, and our display would be much more efficient if we could selectively read bytes from the document rather than wait for the entire document to be downloaded. NPN_RequestRead(), in the NPAPI spec, is specifically for this. The Mozilla engine supports it, IE's ActiveX technology supports the equivalent, but WebKit does not: it has notImplemented(). This is probably more of an enhancement request, but a much-desired one.

NPAPI support is removed from Safari 14 onward and it is not supported in Webkit Builds like WebkitGTK as well. I think this can be marked as "RESOLVED WONTFIX". Thanks!
