Stoping HTTP retry

Hi All,
In our Env we do post using pub.client.http to one of the application. in application logs we can see that webMethods does http post and in case app takes more time to process then it does re-post of the same document which causes multiple document in application.
we tried with making retries in Outbound HTTP Settings section to 0 but then too its retrying once.
has anyone face this issue and let me know any solution for stopping http retry, if application does not response first time to http request.

Thanks in advance,
Atul

You have to be bit more specific about this HTTP retry? To my knowledge webMethods service pub.client.http does not do any retry by itself. Its simple sends data and get response or error. So if you are doing your custom retry logic or using TN to retry delivery provide more and clear details.
