//Last modified: Nov 26th, 06' (New: disable webpage scrollbar, auto hide after x seconds options, 

var interstitialBox={
	
//1) list of files on server to randomly pick from and display
displayfiles: ['/QASFrame.jsp'],


//2) display freqency: ["frequency_type", "frequency_value"]
displayfrequency: ["chance", "1"],

//3) HTML for the header bar portion of the interstitial box
defineheader: '<div class="headerbar"><a href="#" onClick="javascript:interstitialBox.closeit(); return false"><img src="/murad/interstitialBox/closeit.gif" style="border: 0" title="Close Box"/></a></div>',

//4) cookie setting: ["cookie_name", "cookie_path"]
cookiesetting: ["stitialcookie", "path=/"],

//5) bust caching of pages fetched via Ajax?
ajaxbustcache: true,

//6) Disable browser scrollbars while interstitial is shown (Only applicable in IE7/Firefox/Opera8+. IE6 will just auto scroll page to top)?
disablescrollbars: true,

//7) Auto hide Interstitial Box after x seconds (0 for no)?
autohidetimer: 0,
