I'm sure some of you know what I am talking about. IE has a flaw in it that causes a problem with forms on a Linux/Apache server. When you hit a submit button, instead of processing the form, you get a 404 error. If you use the back button and go back to the form and submit again, it goes through.

There is a fix for Linux that corrects the problem created by the IE flaw (Again, Microsoft refuses to correct their own flaw-- what a surprise). The code fix goes in the httpd.conf file.

Does anyone know what code this is that fixes this problem? All of my Cpanel servers do this and it is incredibly frustrating. I used to have Cobalt servers and I had a fix on them, but have forgotten the code fix.

This has worked for me.

1) Open httpd.conf and find:

BrowserMatch &MSIE 4\.0b2;& nokeepalive downgrade-1.0 force-response-1.0

2) Replace it with:

SetEnvIf User-Agent &.*MSIE.*& \ nokeepalive ssl-unclean-shutdown \ downgrade-1.0 force-response-1.0

3) Restart httpd
