Name

ContentType

Synopsis

stringvar = Request.ContentType

Returns a String containing the MIME type of the current client request. On GET requests, this property may return an empty string.

Parameters

stringvar

A String variable to receive the content type.

Example

The example shows how you can take different actions in your page, depending on the ContentType of the request:

Sub Page_Load(  )
   Dim ct As String
   ct = Request.ContentType
   If ct = "application/x-www-form-urlencoded" Then
      'Process form input
      Message.Text = "Form data was submitted."
   Else
      Message.Text = "Content Type of request is: " & ct
   End If
End Sub

The following code can be used to post to the example page:

<html>
   <head>
      <title>Submit a named parameter via POST</title>
   </head>
<body>
   <form id="form1" action="ContentType.aspx" method="POST">
      <h3>Name:</h3>
      <input type="text" name="name">
      <input type="submit">
   </form>
</body>
</html>

Notes

One potential use for this property is to ensure that the content type of the request is what you expect it to be. This can help avoid wasting processor time with invalid requests and prevent malicious users from attempting to forge requests to your application that send unexpected content.
