<section begin="desc" />Set response content type<section end="desc" />


$Web_Type sets the content type for the response.

Syntax

<section begin="syntax" /> %RC = $Web_Type( type ) <section end="syntax" />


$Web_Type is a callable $function (see Calling Sirius Mods $functions), and it takes a single required string argument and returns a status code.

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.
Code Meaning
0 Content type set
-1 Invalid call, not a Web thread
-4 Missing argument

$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.
