I have been playing in the Sandbox, trying to debug an ipn.cgi script. Every time I submit an order, Paypal sends back "several" replies to my script. This is annoying, since it clogs up the logfile in which I have been storing the replies. I could work around this, but it would involve retrieving information from my database about whether the previous reply for this transaction id was 'Pending'. I could also just ignore the problem, and write the new data in my databse on top of the old data. However, I would like to find out if there is a known way to prevent these multiple replies from happening. Any ideas? Professor http://www.professorsopportunities.com

Thanks, Andrew. I seem to remember seeing that somewhere else in the forum, but it wasn't specific enough. Exactly how do you send a 200 OK response? I have googled around looking for an answer, and I have learned a bit about LWP, but I can't seem to find out how to do it.

I'm using the standard coding on my IPN page:

use LWP::UserAgent;
$ua = new LWP::UserAgent;
$req = new HTTP::Request 'POST','http://www.sandbox.paypal.com/cgi-bin/webscr';
$req->content_type('application/x-www-form-urlencoded');
$req->content($query);
$res = $ua->request($req);

I assume that the 200 OK goes in the request object, but don't know how to put it there.

Thanks again, Andrew. I guess I misinterpreted your earlier reply to mean I had to send the 200 OK response myself. That's why I couldn't figure out how to do it -- it's done automatically, and only if my script has no errors.

It appears that the script (the one in my last reply) is now error-free, as I haven't gotten multiple replies in a few days.
