====== Apache - Troubleshooting - Page can not be displayed error on ie ======

===== Error =====

Apache and Microsoft Internet Explorer seem to have a problem with not handling Persistant Connections correctly over https using http/1.1.

If using a scripting language like PHP or ASP (chillisoft) on Apache, sometimes the **Page cannot be displayed** error is shown on posts to other pages.

  * This happens randomly and is a big pain to figure out. 

----

===== Fix =====

Add this line into the **httpd.conf** file, in the section for the SSL virtual host.

<file bash /etc/apache2/httpd.conf>
SetEnvIf User-Agent ".*MSIE.*" nokeepalive ssl-unclean-shutdown downgrade-1.0 force-response-1.0
</file>

<WRAP info>
**NOTE:**  Keep it all on one line!
</WRAP>


Here is the full section from an Apache version 1.3 Apache.conf file.

<file bash apache.conf>
