Server side Request parameters decoding

[Jukka]

Hi all! I want to send the POST request to my asp web server. That POST request contains one parameter, which has cyrillic symbols. When my server recieves that request, it shows me an error window "Value can not be undefined..."

I transform my query string on the client side:

requestString = HttpUtility.UrlEncode(requestString);

But it does not help me. How I need to decode that string on the server side?

Sorry for my English :)

Oh I found the method, wich helped me to convert my client request string correctly.
It is:

requestString = Uri.EscapeUriString(requestString);

After that encoding we do not need to convert request string on the server side
