How could I upload files which are less than 100K only?

Easy enough client-side if your client is happy using ActiveX, and their
security settings will permit it. Something like the following (I haven't
tested this, by the way, but it should be enough to show you how to do
it...)

<html>
<head>

<script language="JavaScript">

function getFileSize(pstrFileSpec)
{
var objFS = new ActiveXObject("Scripting.FileSystemObject");
var objFile = objFS.getFile(pstrFileSpec);
alert(objFile.size + " bytes");
}

</script>

</head>

<body>

<form name="frmTest">
<input type="file" name="txtFile">
<input type="button" name="cmdSize" value="File Size"
onClick="getFileSize(document.frmTest.txtFile);">
</form>

</body>

</html>

Alternatively, you'll have to do it server-side...

This is a IE only 'solution'!
