How to pass POST parameters on launch of a URL

We have a requirement to pass POST parameters in to a URL. Client application wants the parameters to be passed in the body and not as part of the URL.

Launch of a URL in a browser window can only be a GET.

Some SSO protocols do a 'trick' for this by having a GET load a HTML form that looks something like this:

<form ... method="POST">
  <input type="hidden" ... >
  <input type="hidden" ... >
</form>

... and also includes some Javascript to auto-submit the form. It's a bit flickery as it is 2x server trips, and is dependent on the browser having Javascript turned on.

Perhaps you could do something similar? See SAML 1.1 - Browser/POST Profile on Wikipedia for more information on this technique and how it is used in SAML.
