Hello:
First, please try to mention the component you need help with in the Subject line in your message; this will attract those who are capable and willing to answer posts regarding that component.

Now, with that out of the way, here are a few considerations. "Internal Server Error" means just that, the server failed to execute -- on its end -- whatever dynamic content it was requested to. This usually signifies a script error of some sort. If the script error only occurs when you POST from HttpCli, but it works when you post from a commercial browser, then it could be a problem in the way it is being posted -- but still it means that the server-side script is intolerant to posting innaccuracies (maybe its expecting specific values on variables and it explodes when it doesn't get them), so it should be corrected. Wilfried's suggestion should help to find out what is actually being sent to the server in the POST request.

I do not use HttpCli very much (ever?) so I am not familiar with its limitations (if any), but I know that it works pretty well. The only unfamiliar thing I see from your html POST code is a very long (apparently MIME-encoded binary stream) string in the value of __VIEWSTATE. Two things come to mind:
        1. The value is too long for HttpCli to handle in a POST
        2. The value is incorrectly being processed by the server.

First thing is to check if POSTing the page from a commercial browser will work. Second, does anybody know if there are any limitations in the buffer size for POST variables in HttpCli?

        dZ.

Hello Fabian,

The most easy way is to compare your POST data with the POST data that
you do with a browser. You can do that with a packet sniffer. You can
also use SocketSpy (user made page) to view the data.
