Are you accessing this script via SSL? I experienced a similar problem where users would intermittently receive page not found error message with IE while browsing the site via https. The following FAQ fixed the problem.
If you are not using SSL this will have nothing to do with your problem, though looking at your server config file for IE specific conditions might help. -Rob Z. http://www.zwink.net/daid.php >From http://www.modssl.org/docs/2.6/ssl_faq.html#io-ie When I connect via HTTPS to an Apache+mod_ssl+OpenSSL server with Microsoft Internet Explorer (MSIE) I get various I/O errors. What is the reason? [L] The first reason is that the SSL implementation in some MSIE versions has some subtle bugs related to the HTTP keep-alive facility and the SSL close notify alerts on socket connection close. Additionally the interaction between SSL and HTTP/1.1 features are problematic with some MSIE versions, too. You've to work-around these problems by forcing Apache+mod_ssl+OpenSSL to not use HTTP/1.1, keep-alive connections or sending the SSL close notify messages to MSIE clients. This can be done by using the following directive in your SSL-aware virtual host section: SetEnvIf User-Agent ".*MSIE.*" \ nokeepalive ssl-unclean-shutdown \ downgrade-1.0 force-response-1.0 Additionally it is known some MSIE versions have also problems with particular ciphers. Unfortunately one cannot workaround these bugs only for those MSIE particular clients, because the ciphers are already used in the SSL handshake phase. So a MSIE-specific SetEnvIf doesn't work to solve these problems. Instead one has to do more drastic adjustments to the global parameters. But before you decide to do this, make sure your clients really have problems. If not, do not do this, because it affects all(!) your clients, i.e., also your non-MSIE clients. The next problem is that 56bit export versions of MSIE 5.x browsers have a broken SSLv3 implementation which badly interacts with OpenSSL versions greater than 0.9.4. You can either accept this and force your clients to upgrade their browsers, or you downgrade to OpenSSL 0.9.4 (hmmm), or you can decide to workaround it by accepting the drawback that your workaround will horribly affect also other browsers: SSLProtocol all -SSLv3 This completely disables the SSLv3 protocol and lets those browsers work. But usually this is an even less acceptable workaround. A more reasonable workaround is to address the problem more closely and disable only the ciphers which cause trouble. SSLCipherSuite ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP This also lets the broken MSIE versions work, but only removes the newer 56bit TLS ciphers. Another problem with MSIE 5.x clients is that they refuse to connect to URLs of the form https://12.34.56.78/ (IP-addresses are used instead of the hostname), if the server is using the Server Gated Cryptography (SGC) facility. This can only be avoided by using the fully qualified domain name (FQDN) of the website in hyperlinks instead, because MSIE 5.x has an error in the way it handles the SGC negotiation. -----Original Message----- From: Nick Wilson [mailto:[EMAIL PROTECTED]] Sent: Thursday, January 31, 2002 2:33 AM To: PHP-General Subject: Re: [PHP] Re: Page Not Found - on IE -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 * and then Bryan Gintz blurted.... > It was was just the script: > <form name=junk action=script.php method=POST> > > The script was there, and it would work if you refreshed it a bunch, but > then it would give page could not display error ??
