Reading POST-Request-Parameter-Values from WebDynPro now possible?

0 Kudos


in the past I always was disappointed that in WebDynPro there was no way to read POST-request-parameter-values directly after the call of a WebDynPro-Application.

The only (documented) way to read / transfer request-data into an WebDynPro-application was via "URL query string parameters" in the request URL.

The last week I forgot this restriction. I called my WebDynPro-application using a POST-Request-Parameter (cookie_guid) instead of an URL-parameter.

After noticing my mistake, I was really surprised that the WebDynPro could read / shows the the POST-Request-Value.

I didn't make any changes in the coding of my WebDynPro-Application (zvis_show_sso_cookie).

After this cognition I built the following simple HTML-formular to analyse the behavior of the WebyDynPro by calling it with an URL-Parameter (cookie_guid=Url-GUID) together with the POST-Parameter (cookie_guid = Post-Value-GUID).

After calling the WebyDynPro it reads / shows the "POST-Value" of the request !!!

(Remark: If I made a simple refresh or type directly the URL "" in the browser, the same webdynpro reads / shows the URL-Parameter-Value).

<form method="post" action="">

<table border="0" cellpadding="5" cellspacing="0" bgcolor="#E0E0E0">


<td align="right">Cookie_GUID:</td>

<td><input name="cookie_guid" type="text" size="30" maxlength="30" value="Post-Value-GUID"></td>




<input type="submit" value=" Absenden ">

<input type="reset" value=" Abbrechen">







My questions:

I there any documentation that describes the behavior of WebDynPro after calling it by using POST-Parameter values?

I believe in the past it wasn't possible to read POST-request-parameter-values in WD. Has SAP changed the functionality?

Is the behavior I described in my example above mandatory?

As far as i know in general HTTP request GET method is standard but in SAP POST is standard. All the client request is passed as POST to the server in order to avoid the URL parameter length restriction in GET method.
