Hi.
So I have this HTML file that tests the user's screen resolution, and plugins installed using Javascript. So when the user accesses the page it sees: (e.g.) Your current screen resolution is 1024x768 and you have the following plugins installed: Plug-in No.2- Java Deployment Toolkit 7.0.10.8 [Location: npdeployJava1.dll], Plug-in No.3- Java(TM) Platform SE 7 U1 [Location: npjp2.dll], Plug-in No.4- Microsoft Office 2003 [Location: NPOFFICE.DLL]... I also need to save this information in a file on the server. All users are having firefox or chrome. How do I do this considering javascript can't write files on the server. I also don't want to use activex. Is there a way to redirect the javascript output to php?

<html>
<body>
<script language="JavaScript1.2">
document.write("Your current resolution is "+screen.width+"*"+screen.height+"")
</script>
<BR><BR>
<SCRIPT LANGUAGE="JavaScript">
var num_of_plugins = navigator.plugins.length;
for (var i=0; i < num_of_plugins; i++) {
var list_number=i+1;
document.write("<font color=red>Plug-in No." + list_number + "- </font>"+navigator.plugins[i].name+" <br>[Location: " + navigator.plugins[i].filename + "]<p>");
}
</script>
</body>
</html>

Thanks
