Set response content type
$Web_Type sets the content type for the response.
$Web_Type is a callable $function, and it takes a single required string argument and returns a status code.
Syntax
%rc = $Web_Type( type )
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. |

Status codes
Code | Meaning |
---|---|
0 | Content type set |
-1 | Invalid call, not a Web thread |
-4 | Missing argument |
Examples
Sample code follows:
%x = $Web_Type('image/gif')
The above line sets the content type to CompuServe GIF format (a binary image).
Note: 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 the TYPE subcommand of the JANUS WEB command. In this case, a $Web_Type call would not be needed unless the type was being changed from that default.
