Fetch Parameter from Typo3 to ITS

Hi Everybody

I talk about a Standalone ITS Version 6.20 6200.1004.33246.0

What I want:

I want to logon automatically from a Typo3 to an ITS- Transaction.

Background:

Let's say that Parameters like username and password are defined in a TYPO3 Session.

Now, I would like to pass those two parameters to the ITS to logon a known internet user (SU05) with a form like this:

<form action="http://sapits:9800/scripts/wgate/zvw01e/!" method="post" name="app0_de" target="_top">

<input type="hidden" name="~language" value="DE">

<input type="hidden" name="~G_WWCC_CUSTOMER" value="customer">

<input type="hidden" name="~G_WWCC_PASSWORD" value="pass">

<input type="submit" value="start ITS">

Issue:

unfortunately, I cannot see the parameters (beside ~language) on the ITS- Side.

Must that be handled by reading the session? or reading cookies?

And when yes, how someone did that?

any thoughts?
