	This is sample code from an application that sends a slightly different form (that is processed with a "method=GET") to Netscape browser users than it does to other browsers. <var>$Web_Num_IsIndex</var> is used to detect the number of fields on the form, and to route processing accordingly. This example uses the fact that for some reason the number of isindex fields returned will by 7 for Netscape clients but some other number for other browsers. To more precisely determine what browser the client is using, use "$WEB_HDR_PARM('USER-AGENT')".

	$Web_Num_IsIndex retrieves the number of isindex fields in a URL.		<var>$Web_Num_IsIndex</var> retrieves the number of isindex fields in a URL.

	Since isindex fields are more commonly called "URL parameters,", you may want to use the synonym for this $function, <var>[[$Web_Num_URL_Parm]]</var>.
