Weirdness with Plone and Apache 2.2
While migrating one Plone 3 site to another server I got some unexpected configuration issues.
I have just migrated the python.org.mx site to another server. It has a Plone
3.3.5 site with PloneHelpCenter and a Planet Aggregator for blogs. There’s a
Varnish instance in the middle. Moving this site was very strightforward
except for a unexpected Apache configuration directive for mod_proxy.
Normally we used this mod_rewrite directives to make the magic happen:
RewriteEngine On
RewriteRule ^/(.*)/$ http://127.0.0.1:8080/VirtualHostBase/http/%{HTTP_HOST}:80/PythonMexico/VirtualHostRoot/$1 [L,P]
RewriteRule ^/(.*) http://127.0.0.1:8080/VirtualHostBase/http/%{HTTP_HOST}:80/PythonMexico/VirtualHostRoot/$1 [L,P]
But that wasn’t enough for Apache 2.2 and the Proxy redirection was not being made resulting in a error like this:
[Mon Oct 11 23:24:08 2010] [error] [client 220.181.94.228] client denied by server configuration: proxy:http://127.0.0.1:8080/VirtualHostBase/http/www.pythonmexico.org:80/PythonMexico/VirtualHostRoot/
After some testing I realized that I had to explicity allow the reverse proxy to varnish:
<IfModule mod_proxy.c>
<Proxy proxy:http://127.0.0.1:8080/>
Order deny,allow
Allow from localhost
</Proxy>
</IfModule>
So, that’s it !
