Apache https redirection results in 400 error

Question

This issue is happening on a Red Hat instance. The apache installed is version [Apache/2.2.19] and the mod_ssl version is [2.2.16.] HTTP access works fine, but when mod_rewrite is enabled for http to https redirection, it results in following 400 Error:

Bad Request

Your browser sent a request that this server could not understand.
Request header field is missing ':' separator.

The error in Apache's error_log file is:

request failed: error reading the headers

The similar setup is working in another environment. Can someone please help me to resolve this.

Thanks Noman A.

Found solution for this.

It appears that the reboot of the system updated my yum packages, including httpd [2.2.22] which was conflicting with my Apache installation [2.2.19].

I updated the mod_ssl.so [2.2.16] in my Apache to mod_ssl.so [2.2.22] and the error was resolved.

How did you update it? In which directory is this file? – Traveling Salesman Feb 27 '15 at 13:19
Yeah, how did you update it exactly? How do I know to check for the version of ssl that might be causing this by looking at my php info file? Thx – marciokoko May 11 '15 at 23:02

Updating mod_ssl and httpd fixed this issue for us too. Thanks to all who contributed.
