AS2 Domain Lock – Protecting SWF Files

yuzi — Wed, 22 Jun 2011 15:43:36 +0000

Domain Locking is the simple way to protect your swf files at least from newbies. Here’s what i’ve found for domain locking. Just copy and paste this code into first frame;

urls_allowed = ["www.guidefordesign.com"];
sitelock(urls_allowed);
function sitelock(urls_allowed) {
lock = true;
domain_parts = _url.split(”://”);
real_domain = domain_parts[1].split(”/”);
domain.text = real_domain[0];
for (x in urls_allowed) {
if (urls_allowed[x] == real_domain[0]) {
lock = false;
}
}
if (lock) {
_root._alpha = 0;
}
}

for multiple domain lock just change the line above;

urls_allowed = ["www.guidefordesign.com","www.anotherdomain.com"];

yuzi — Sat, 17 Oct 2009 21:36:14 +0000

As you know when you upload new swf file to server, browser doesn’t show it until you delete browser cache. Also it’s important to delete swf cache for websites which includes dynamic data and dynamic sub swf files. Here’s the method that we pass this problem for flash.

Now we’ll make some changes on AC_RunActiveContent.js file. ( Supported with CS3, for older versions you need to download it from here )

1.open AC_RunActiveContent.js file

2. Change AC_FL_RunContent() function with this;

function AC_FL_RunContent(){
var ret =
AC_GetArgs
( arguments, “.swf?foo=”+new Date()+”" //<–Line we pass the browser by giving auto generated numbers
, “movie”, “clsid:d27cdb6e-ae6d-11cf-96b8-444553540000″
, “application/x-shockwave-flash”
);
AC_Generateobj(ret.objAttrs, ret.params, ret.embedAttrs);
}

3.That’s all..

How to delete xml cache with actionscript?

yuzi — Wed, 14 Oct 2009 13:25:12 +0000

İt’s important to delete xml cache in flash if your content is renewing it self often. Here’s the sample code for deleting xml cache with actionscript;

Just change your xml loading code with this:

xmlData = new XML();
xmlData.ignoreWhite = true;
xmlData.onLoad = loadXML;
myAdd=Math.round(Math.random()*10000); // producing random numbers to add after filename
myXmlFile=”myfile.xml?new=”+myAdd; // little trick to pass the browser cache, it thinks this is a new file ..
xmlData.load(myXmlFile);

With this code your flash will reload your xml file refreshing everytime.
