Maybe. Mark S. suggested the same thing. The default POST header for 
Content-Type is "application/x-www-form-urlencoded", which is what he 
uses. I believe content-length is also sent by default. I don't know 
what other things should be sent in the headers, but would like to know.

The thing is, the POSTs and responses do go through. Everything appears 
to work; I get the data and PayPal responds to my POST correctly. The 
only thing that doesn't work is (apparently) no response code is sent. 
The one exception are script errors, where PayPal does register an error 
500. Othewise no codes appear in PayPal's history.

If it weren't for the fact that PayPal continues to resend requests so 
many times, I'd just forget about it. I have all the data I need, and 
it's verified. For now, I've put a check into the script that just drops 
duplicate resends silently. That works, but I'd rather the server didn't 
get hit on so much. After enough resends, PayPal registers a failure and 
stops, but I'm not sure how many failures it will allow before it 
decides my server isn't operative and drops the account. I don't even 
know if that's how it works, but I don't want to chance it.
