Steps to reproduce

  1. Install one service with CA license file.(The service can process post request and then redirect to another url)
  2. Don’t import public key into local environment and then use Edge to open the following html.
    <head><meta http-equiv="cache-control" content="no-cache" /><meta http-equiv="pragma" content="no-cache" /></head>
    <body onload="document.forms[0].submit()“>
    <script language="javascript">document.write(“Please wait …”);</script>
    <noscript><p>Note: Your browser does not support JavaScript or it is turned off. Press the button to proceed.</p></noscript>
    <form method="post” action="https://ip:port/serviceurl" >
    <input type="hidden" name="SAMLRequest" value="PEFMDAxLzA0L3htbGVuYyMiIHhtb"/>
    <input type="hidden" name="RelayState" value="ROLE_SBO"/>
    <noscript><input type="submit" value="Continue"/></noscript></form>

    • When I import corresponding CA license file into system, then Edge can process the post request and working normally.

    • This works in all other major browsers.

    • While I use “GET” or “PUT” in the form, the service can receive the request and process it.

    • If you use debug command, and refresh the url for several times, it may work, but most time in debug mode, it doesn’t work. If you don’t open debug command, it will reproduce.
