I'm setting up a reverse proxy system with Apache 2.2.8 on Ubuntu JeOS
8.04.1, and using mod_proxy_html. We have multiple backend servers,
Apache identical to our proxy setup, and IIS.
Our root site requires the use of mod_proxy_html which makes it active
for every sub-directory on the system. The issue we are having is
that some of our pages served from IIS are malformed and the
autocorrection features of mod_proxy_html end up showing us just how
malformed they are. Ideally we would clean up the HTML, but we are
looking at literally hundreds of sites with different 'owners.' Of
course the whole point of this is that we are slowly migrating
sections of our website to the apache systems and using CMS solutions
for publishing, so in the long run this issue will be moot, but for
the time being it is a big deal.
It would be perfect if I could add an entry in the virtual host file
for a specific Location that turns off the mod_proxy_html features
completely. Luckily most of the sites that have this issue use only
relative links and the normal ProxyPassReverse covers them well. I
have yet to find a way to do this though, so I thought I would ask
here if that is possible.
In the mod_proxy_html documentation it says that some cleanup will not
be done if you do not specify a Doctype, or if you specify a custom
Doctype, however even when I tried that some tags are being
corrected. One big one is unclosed <p> tags. mod_proxy_html is
adding the closing </p> since the tag was unclosed, however it is
putting it in the wrong place since it of course can't tell where it
was intended to be.
Here are some selected highlights from my virtual host file:
ProxyPass / http://backendserver
ProxyHTMLURLMap http://backendserver http://proxyserver
<Location />
ProxyPassReverse http://backendserver
SetOutputFilter proxy-html
</Location>
## subfolder
ProxyPass /subfolder http://backendserver2/subfolder
ProxyHTMLURLMap http://backendserver2/subfolder /subfolder
<Location /greek2>
ProxyPassReverse http://backendserver2/subfolder
SetOutputFilter proxy-html
ProxyHTMLURLMap /subfolder /subfolder/
ProxyHTMLURLMap /subfolder /subfolder
</Location>
I've tried removing the ProxyHTMLURL and OutputFilter directives, but
since the root folder being served by the proxyserver has those
options set they also apply then to the subfolder. Is there a way to
stop mod_proxy_html from not running at all within that subfolder? Or
is there a way to completely kill its seemingly mandatory cleanup
features for a subdirectory?
Thanks for any help.
