| type | The content type indicator. It must be non-null. Janus Web Server makes no assumptions about what a valid type is, and it will set content type to any user-specified string. The HTTP specification (browsable at http://www.w3.org) states that content type should be case insensitive. |

$WEB_TYPE return codes
Sample code follows:
%X = $Web_Type('image/gif')
The above line sets the content type to CompuServe GIF format (a binary image).
You can also set the content type for all output presented in response to a given URL or pattern, if it is not already set, by using theTYPE subcommand of the JANUS WEB command, as described in . In this case, a $Web_Type call would not be needed unless the type was being changed from that default.
