Subject: [users@httpd] Issue with mod_proxy_html or mod_xml2enc after upgrade


Hello all=2C
I'm running apache 2.2.11 on a rhel 5 OS.
I've set it up as a reverse proxy based on mod_proxy_html 3.0 initially wit=
hout any problem.
I've upgraded to version 3.1 yesterday evening... and now=2C it's broken fo=
r only one reverse proxy entry.
In order to upgrade=2C I have:
- downloaded mod_proxy_html
- shutdowned httpd
- compiled mod_proxy_html and mod_xml2enc
- modified the vhost entries to replace all SetOutputFilter proxy-html entr=
ies by ProxyHTMLEnable On
=20
My first problem was that I have been building mod_xml2enc v 1.0.2 which se=
g faulted. So I've been upgrading to v1.0.3.
The seg fault logs have disappeared but the reverse proxying is still not w=
orking.

First=2C an extract of my vhost configuration:
<VirtualHost 172.17.1.6:8443>
        DocumentRoot /var/www/localhost/sites/website
        CustomLog /var/log/httpd/website/apache.log combined env=3D!VLOG
        ErrorLog /var/log/httpd/website/error_log
        ServerName website
        SSLEngine on
        SSLCertificateFile /etc/httpd/ssl/ssl.crt/website.crt
        SSLCertificateKeyFile /etc/httpd/ssl/ssl.key/website.key
        SSLCertificateChainFile [...] classic SSL config
        ProxyRequests off
        LogLevel Info
        ProxyHTMLLogVerbose On
ProxyPass       /portal/                                                 ht=
tp://internalServer:8180/portal/
        ProxyPassReverse       /portal/                                    =
      http://internalServer:8180/portal/
        ProxyHTMLURLMap http://internalServer:8180/portal                  =
     /portal
        <Location /portal/>
                ProxyHTMLEnable On
                ProxyHTMLDoctype XHTML Legacy
                ProxyHTMLExtended On
                RequestHeader   unset   Accept-Encoding

</Location>
=20
</VirtualHost>
=20
Now=2C the issue: the reverse proxy fails on the following packet:
Hypertext Transfer Protocol
 HTTP/1.1 302 D\351plac\351 Temporairement\r\n ("Moved Temporarily" in fren=
ch)
 Server: Apache-Coyote/1.1\r\n
 Set-Cookie: JSESSIONID=3DE5724288C24973ECCEBB42B2BD7CEEF2=3B Path=3D/porta=
l\r\n
 Location: http://internalServer:8180/portal/public/classic/\r\n
 Content-Type: text/html\r\n
 Content-Length: 0\r\n
 Date: Tue=2C 27 Apr 2010 10:55:33 GMT\r\n
=20
=20
I get this packet when i perform a network capture between the reverse prox=
y and the internal server.
When i perform the capture between my computer and the reverse proxy=2C I s=
ee the GET /portal command but no answer.
=20
One other point:
The url https://website:8443/portal/public/classic also performs a 302 redi=
rection to /foo context root=2C but the Location header is set to https://w=
ebsite:8443/foo instead of http://internalServer:8180/foo. in this case=2C =
the redirect is working.
=20
If I set ProxyHTMLEnable Off in the location tag=2C everything is working.
=20
The problem is that I don't get any log generated for this problem.
=20
Please note that all this is the only web app that fails (and of course the=
 most critical=2C it wouldn't be funny otherwise!)
=20
Thanks in advance for your help=2C
