PHP 4.0 Bug #7375: In PHP versions later than 4.0.1pl2, IE reports a 404 error for script

From: webmaster@jwdx.com Operating system: RedHat 6.1 PHP version: 4.0.3 PHP Bug Type: Scripting Engine problem Bug description: In PHP versions later than 4.0.1pl2, IE reports a 404 error for script $url = getenv("REQUEST_URI"); $dest is taken from a mysql database $goto = "http://" . "$dest" . "$url"; <html><head> </head> <frameset rows="100%,*" frameborder="no" border=0><frame name="webmapper" src="<? echo("$goto"); ?>" noresize></frameset> </html> This should be enough to get the idea across. Basically it is a redirection script. I have 404 errors pointed to this file, so when a person goes to a domain pointed to me that has a REQUEST_URI, that get added to the end of $dest so it takes them to that file in whatever directory they are pointing to. When i use headers("Location: $dest" . "$url"); it works fine. In Netscape, it works fine, but in IE it displays a 404 error. When I changed back to 4.0.1pl2, it worked fine. What could have changed to make this happen? Is there anything I can do to prevent this problem? -- Edit Bug report at: http://bugs.php.net/?id=7375&edit=1
