Posting Data to ASP.NET
Device Side
To post data to an ASP.NET page, the device side code is the same as what you would use for any other backend technology:
req = Ajax("/sendData_ajaxPost.aspx", "POST", "myText=" & txtSend.value)
See Ajax and Ajax made Simple for more information.
Server Side
There are many ways to process the data using ASP.NET. The simplest is to embed code in the .aspx file. For example:
<%
Dim myText as String
myText = Request.Form("myText")
'Additional processing of myText here...
%>
<html><body>
<p>myText is: <%=myText%></p>
</body></html>
There are several tutorials online that deal with various ways of processing requests with ASP.NET.
