Hi Nicolas,
I followed your recommandation, still having the same issue.
I had the message:
Invalid command 'ProxyHTMLEnable' when restarting apache.
In fact, it seems to be related to my problem, as response from html
server systematically removed /virtuoso/.
This module may not be installed by default on every distro and some
older versions do not ship it at all.
On Fedora i also had to install it separately.
You can try searching for mod_proxy_html using apt-cache on Debian.
After investigating on the web, I found the following hack:
"Have you tried leaving out "ProxyHTMLEnable on" entirely? I think
that directive is new and not in the version in Ubuntu.Do put
"SetOutputFilter proxy-html" in its place".
I tried and ... it works ;)
Going now investigating further to be sure that everything is OK.
Good to hear. I will have a look what the difference between this and
the ProxyHTMLUrlMap is.
Thank you very much for providing me the configuration file.
No problem. I will add this as a suggestion into the documentation so
others may benefit.

Hi Nicolas,
I'm trying to access virtuoso server through an apache server, using
mod_proxy.
Calling http://www.mysite.net/virtuoso, it should redirect on my local
server on 88.191.91.72:8890 <http://88.191.91.72:8890>
NameVirtualHost 88.191.91.72
<VirtualHost 88.191.91.72>
ServerName www.mysite.net <http://www.mysite.net>
...
ProxyRequests off
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
ProxyPass /virtuoso/ http://172.16.12.128:8890/
ProxyPass /virtuoso http://172.16.12.128:8890
ProxyPassReverse /virtuoso/ http://172.16.12.128:8890/
ProxyPassReverse /virtuoso http://172.16.12.128:8890
ProxyTimeout 300
ProxyHTMLURLMap /virtuoso/ http://172.16.12.128:8890/
ProxyHTMLURLMap /virtuoso http://172.16.12.128:8890
ProxyPreserveHost On
</VirtualHost>
But doing so, when trying to enter login and password for virtuoso
login, from http://www.mysite.net/virtuoso/conductor (with expected
screen).
I have an error with a returned address
http://www.plm-interop.net/conductor/main_tabs.vspx, and a message
"Not
found".
I think it does not work, because some call are may be not done under
the path /virtuoso , in particular with the login, but I'm not so
sure.
Did some one already address successfully this need (redirection on a
server) and can indicate me how to proceed?
I think your ProxyHTMLURLMap arguments are in reverse order.
The following should work:
NameVirtualHost 88.191.91.72
<VirtualHost 88.191.91.72>
ServerName www.mysite.net <http://www.mysite.net>
...
# Disable global proxy
ProxyRequests Off
# Pass original host to Virtuoso
ProxyPreserveHost On
# Timeout waiting for Virtuoso
ProxyTimeout 300
# Set permission
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
#
# Map /virtuoso/ to a local Virtuoso instance.
#
# Since ProxyPass and ProxyPassReverse only fix the Headers
# of the request, we need to use ProxyHTMLURLMap to rewrite
# content.
#
<Location /virtuoso/>
ProxyPass http://172.16.12.128:8890/
ProxyPassReverse /
# Enable rewrite rules
ProxyHTMLEnable On
ProxyHTMLURLMap / /virtuoso/
ProxyHTMLURLMap http://172.16.12.128:8890/ /virtuoso/
# Uncomment this when EnabledGzipContent=1 in virtuoso.ini
#SetOutputFilter INFLATE;DEFLATE
</Location>
</VirtualHost>
If we map the virtual host straight through to Virtuoso, we only
need header rewriting and save the time/cpu power to rewrite the
content.
#
# Map / to a local Virtuoso instance
#
# Since paths are mapped straight through, we do not have to
# rewrite the content.
#
<Location />
ProxyPass http://172.16.12.128:8890/
ProxyPassReverse /
</Location>
Note that the next version of Virtuoso OpenSource has a couple of
patches to fix some issues with running under a reverse proxy, so
you may need a newer version of Virtuoso.
Please contact me if you continue to experience problems and i will
make a new snapshot available to you.
