clear querystring value

[marky777]

Hi. Does anyone know how to remove/clear a certain value/key from a querystring? Request.QueryString.Clear(); AND Request.QueryString.Remove(key);, do not work as the error states that QS is read only? I do want to do the response.redirect("test.aspx?q=''") thing, as my it will not work for my situation. Any help would be appreciated. Thanks M
