Response.ContentType

ASP Response Object : ContentType Property

The ContentType property specifies the HTML content type for the response. The content type is a string of the form form/subform, where type is the general content category and subtype is the specific content. The default is text/HTML.
Example:

  <% Response.ContentType = "text/plain" %>

  content-type: text/plain

A complete list of valid content types is registerd with the IANA (Internet Assigned Numbers Authority). The list can be accessed at:

Note: Non-standard and experimental types are not included in the list. Types that follow the format "x-typename" are experimental types.
