Subject: [users@httpd] 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.
[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.

>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<http://www.bpocenter-hp.com>

hello hello hello,
Ive seen exactly that behavior many times in 2.2.29. Once
ProxyHTMLEnable is invoked in a vhost, output is heavily influenced,
eventhough there are no rules to define modification of any html at
all.. The rules i define works flawlessly, but the filter invocation
swallows more than it should... i have been pulling my hair for this
problem, with the result of light baldness...
I wasnt aware of the bug report - yet, i am not sure, whether it applies
a fix at some point for the 2.2 branch - anyone to know this ?

Hello Yann,
Thanks for your reply.
I'll review this link. It's really possible that it's related
I'll post my findings later.
Thanks.

Hi Nick,
Thanks for the answer.
Mod_ xml2enc is loaded in the httpd.conf:
LoadModule xml2enc_module modules/mod_xml2enc.so
Besides that, what do you mean with a "broken backend"?
Atte.

It appears you need mod_xml2enc in there. It deals with precisely that problem.
You might also have an issue with a broken backend, though I can't tell that from what you posted.
