Name
HttpMethod
Synopsis
stringvar = Request.HttpMethod
Returns a String containing the method (i.e., GET, POST, or HEAD) of the current request.
Parameters

Response.Write("HEAD requests not allowed!<br/>")
Response.End
Case "GET"
'Process request

Calling Response.End will immediately terminate processing of the page, which will also prevent rendering of any server control output. The code for a page that makes a POST request to the example page is shown here:
<html>
<head>
<title>Submit a named parameter via POST</title>
</head>
<body>
<form id="form1" action="HttpMethod.aspx" method="POST">
<h3>Name:</h3>
<input type="text" name="name">
<input type="submit">
</form>
</body>
</html>Notes
In classic ASP, the request method was typically retrieved using the
REQUEST_METHOD key of the ServerVariables collection. Often, this key was used to create self-submitting form pages by displaying a set of form fields when the GET method was detected and processing the ...
