I have a frame that refreshes every 10 seconds. The called script does a session_start(), and displays a log-out button when there is a valid session. After a random number of refreshes, netscape outputs "Document contains no data" instead of the correct content, even though everything is fine with the script. When i reload that specific frame, it works again. My environment is php 4.0.3pl1 with apache 1.3.12, but a couple of friends of mine ran over that bug too on other, different environments... Here is the script: ========================================================== <?$nodebug=1;$need_db=1;include "./lib/config.php"; session_start(); ?> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <html> <head> <title></title> </head> <link rel=stylesheet type="text/css" href="./lib/style.css"> <meta http-equiv="refresh" content="15; URL=topbar.php?PHPSESSID=<?if (isset($PHPSESSID)&&$PHPSESSID!="") echo $PHPSESSID;?>"> <body bgcolor="#ffffff" text="#000000"> <span class="f-8"> <div align="right"> <? if (isset($PHPSESSID) && $PHPSESSID != "" && $REMOTE_ADDR == $ip) {?> logged in<br> <a href="logout.php" target="_top">log out</a> <?}?> </div> </span> </body> </html> ========================================================== config.php sets some variables I use over the whole site. It happens to other scripts as well, but this frame construction makes it happen quite often (because of the refresh).
