swf広告ストラテジ
DBで&nbsp;<script defer='defer;'>必須

IEの場合
1) document.writeを空functionで上書きして書き込みを抑制し、innerHTMLに挿入する
# 抑制しないと2回書き込みかつ1回目でdocument rootに書き込まれてしまう
2) reEvalでscriptタグを取得してdocument.writeをさらに上書きして書き込む
# この際に&nbsp; / deferをやってないとscriptタグが取得できない

Fx、その他の場合
1) innerHTMLに挿入する
2) reEval

問題点
IEの場合明らかに2度走ってる。
