If you embed your DjVu document in an HTML page, the tags you use give you an easy way to access the plug-in scripting interfaces; but if you serve the document directly off the Web server there are no such tags. However, the plug-in/control reads "CGI-style" arguments that allow you to set properties as part of the URL that instantiates it.
To specify a CGI-style argument, append "?djvuopts&" to the document's URL and separate property assignments with “&” signs.
