Hi,

I'm using default Ubuntu server 9.01 and Apache as a reverse proxy.
For certain countries the visitors must be served a fixed url, so I use GeoIP to check the ip of the visitor and redirect accordingly.
However, as disk cache fills up it seems that the proxy server is returning a (cached ?) page before it's going through the rewrite rules.

The Apache config is like this:

<Virtualhost 1.2.3.4:80>

GeoIPEnable On
GeoIPScanProxyHeaders On
GeoIPDBFile /var/www/GeoIP.dat

RewriteEngine On

RewriteCond %{ENV:GEOIP_COUNTRY_CODE} ^(nl|be|de)$ [NC]
RewriteCond %{HTTP_HOST} !^(nl|be|de|www)\.domain\.com$ [NC]
RewriteRule ^(.*)$ http://www.domain.com/$1 [L]

ProxyRequests Off

<Proxy *>
Order deny,allow
Allow from all
</Proxy>

ProxyPass / http://127.0.0.1:8080/
ProxyPassReverse / http://127.0.0.1:8080/
ProxyPreserveHost On

CacheRoot /cacheroot
CacheEnable disk /
CacheMaxFileSize 10000000
CacheDirLevels 5
CacheDirLength 1
CacheDisable www.domain.com

</VirtualHost>

If I do a wget with an empty cache disk this is the result:

wget http://nl.domain.com/
Resolving nl.domain.com... 1.2.3.4
Connecting to nl.domain.com|1.2.3.4|:80... connected.
HTTP request sent, awaiting response... 302 Found
Location: http://www.domain.com// [following]
Resolving www.domain.com... 1.2.3.4
...

Looks good...

But after a few wgets it turns out to be this:

wget http://nl.domain.com/
Resolving nl.domain.com... 1.2.3.4
Connecting to nl.domain.com|1.2.3.4|:80... connected.
HTTP request sent, awaiting response... 200 OK
Length: 36330 (35K) [text/html]
Saving to: `index.html'

It does not rewrite, but seems to be served directly from the disk cache... anyone any ideas how to fix this ?

Cheers,
Poard
