title: Saving data using ajax: sending large text in querystring is good or bad?
body: <p>I want to add a comment feature in my ASP.NET website  that is similar in stackoverflow.com. Here the entire page is not getting posted, instead ajax is being used i hope.How does the value entered inside the textarea is passed to the server page ? as querystring for an ajax get/post call ? .I believe its not a good idea to do so when the content of the text area (text ) is large in size . How can i pass special characters  ?
  Whats is the best method to do this ?  Please advice</p>
