RESOLUTION

Append post information onto the end of the URL and use NPN_GetURL instead.

For example, instead of this

   NPN_PostURL(instance, "http://url", "", 9, "postdata", FALSE);

Use this

   NPN_GetURL(instance, "http://url?postdata", "");

There is an upper limit of 2k on a GET URL. For larger amounts of POST data, there is no workaround available at this time.
