I'm trying to create an HTTP Post button to a site that has an html page as an example. Posting via the built in HTML Post button doesn't seem to format it correctly for this site. Can I do it with a javascript function? What would that look like so I have the fields on my form pull and load? I tried doing it by contatenating a URL string but acrobat crops the url at 1054 char and I need to be able to pass a long string. So I am trying to do it another way through HTTP Post. Also, HTTP Post won't have the same URL length restriction will it? Here is the example their website provides.
<html>
<head>
<title>Pre-Filled PowerForm Sample</title>
<style type="text/css">
body { background-color: #fefdfc;}
p.description { width: 500px; border: 1px solid #cfc; padding: 20px; }
.form_submit { text-align: right;}
.form_cont { border: 1px solid #cfc; padding: 20px; width: 500px; background-color: #cd9;}
.top_cont { width: 550px; margin-left: auto; margin-right: auto; }
</style>
</head>
<body>
<div class="top_cont">
<p class="description">This web form, when submitted, will open a DocuSign Web PowerForm with all of the entered data. This allows the user to review the finalized document and apply their DocuSignature.</p>
<div class="form_cont">
<form action="https://demo.docusign.net/MEMBER/PowerFormSigning.aspx?PowerFormId=8968380d-16da-447c-97d7-fa989ed11..." method="POST">
