Apache Reverse Proxy deletes <meta http-equiv=“Content-type” content=“text/html; charset=utf-8” /> from code (Apache Users)

Hello to everyone,

this is my first post here.

I've already searched the forum for a related issue, but none of the results seems to solve my issue.

My systems setup is as follows:

There is a MS Sharepoint 2013 served on IIS 7 in an internal customer network. This seems to behave correctly from within the internal network.

To make this service public, I have an apache 2.2 server running on Red Hat EL 6.0 on a DMZ. The apache has a virtual host configured as Reverse Proxy to allow the conections from outside.

Due to some links problems i found, I had to compile and integrate mod_proxy_html module to parse those Links.

cid:image001.png@01D0995E.376D7440 The problem is that I see strange characters when accessing from outside (through the apache). And it seems to be due to Apache erasing an html meta tag.

cid:image003.png@01D0995E.F44D3320

From inside the MZ, the html code starts:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

However, when accessed from outside, the html code starts:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

Tag missing: meta http-equiv="Content-type" content="text/html; charset=utf-8".

I have already tried adding to my httpd.conf:

AddDefaultCharset utf-8

ProxyHTMLCharsetOut utf-8

ProxyHTMLMeta On

The virtualhost is configured as follows (130.177.97.99 is the IP belonging to the backend):

ServerName www.bpocenter-hp.com

SSLProtocol -all +TLSv1

SSLCipherSuite HIGH:MEDIUM:!aNULL:!MD5
