Hmm, just figured out something. When you POST an IPN verification to Paypal's servers and you get this huge HTML page back instead of the expected "VERIFIED" or "INVALID", it may be because your query didn't have a content-length header. This is probably in the w3 documents, I didn't RTFS. Anyway, now I can hopefully get the IPN stuff working.
