 ====== 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>
