Changing the Form Resubmit Duration in High Level API

One of our vendors is having issues with how quickly the form is resubmitted when waiting for a response (IdP to SP SSO). Is there a way to change how often the form reposts (I am assuming in the configuration)?

There is only a single post to the service provider.
Once the user is successfully logged in at the identity provider, an HTTP response is returned to the browser.
This HTTP response contains an HTML form with a hidden form variable that is the encoded SAML response.
A small section of JavaScript automatically posts this to the service provider.
The HTTP post to the service provider occurs once.
There is no looping or resubmission etc.
