[users@httpd] Issue with mod_proxy_html or mod_xml2enc after upgrade
Hello all,
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 without any problem.
I've upgraded to version 3.1 yesterday evening... and now, it's broken for only one reverse proxy entry.
In order to upgrade, 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 entries by ProxyHTMLEnable On
My first problem was that I have been building mod_xml2enc v 1.0.2 which seg faulted. So I've been upgrading to v1.0.3.
The seg fault logs have disappeared but the reverse proxying is still not working.
First, 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=!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/ http://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>
</VirtualHost>
Now, 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 french)
Server: Apache-Coyote/1.1\r\n
Set-Cookie: JSESSIONID=E5724288C24973ECCEBB42B2BD7CEEF2; Path=/portal\r\n
Location: http://internalServer:8180/portal/public/classic/\r\n
Content-Type: text/html\r\n
Content-Length: 0\r\n
Date: Tue, 27 Apr 2010 10:55:33 GMT\r\n
I get this packet when i perform a network capture between the reverse proxy and the internal server.
When i perform the capture between my computer and the reverse proxy, I see the GET /portal command but no answer.
One other point:
The url https://website:8443/portal/public/classic also performs a 302 redirection to /foo context root, but the Location header is set to https://website:8443/foo instead of http://internalServer:8180/foo. in this case, the redirect is working.
If I set ProxyHTMLEnable Off in the location tag, everything is working.
The problem is that I don't get any log generated for this problem.
Please note that all this is the only web app that fails (and of course the most critical, it wouldn't be funny otherwise!)
Thanks in advance for your help,
Pierre Casenove

Does it fix your problem if you uncomment that line and recompile?
