I used a cgi to generated a HTML page. It works fine normally. But sometimes under IE 4.01, I saw an extra ASCII character got printed on the screen at the end of the page. However, when I view the source, there is nothing there. I even used a Protocol Analyzer to see the actual packet. But there is nothing after the </HTML> tag. It nerver happens to Netscape. Is this a IE bug? If it is, what's causing it?
