Subject: Apache Reverse Proxy deletes <meta http-equiv=“Content-type” content=“text/html; charset=utf-8” /> from code
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.
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.
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">
<html
dir="ltr" lang="es-ES">
<head><meta http-equiv="X-UA-Compatible" content="IE=10" /><meta name="GENERATOR" content="Microsoft SharePoint" /><meta
http-equiv="Content-type" content="text/html; charset=utf-8" /><meta http-equiv="Expires" content="0" /><meta name="msapplication-TileImage" content="/_layouts/15/images/SharePointMetroAppTile.png" /><meta name="msapplication-TileColor" content="#0072C6"
/><title>
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">
<html dir="ltr" lang="es-ES">
<head><meta http-equiv="X-UA-Compatible" content="IE=10" /><meta name="GENERATOR" content="Microsoft
SharePoint" /><meta http-equiv="Expires" content="0" /><meta name="msapplication-TileImage" content="/_layouts/15/images/SharePointMetroAppTile.png" /><meta name="msapplication-TileColor" content="#0072C6" /><title>
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):
<VirtualHost bpocenter-hp:5445>
ServerName
www.bpocenter-hp.com
SSLProtocol -all +TLSv1
