Happy Holidays !
I am trying to implement an eror page server using mod_rewrite. The basic
premise is that if the Apache proxies for our application go down, the network
load balancer will redirect traffic to this Apache server. The server will pop
up an application specific message, depending on the value of %{HTTP_HOST}
So for example, inside our htdocs I may have the follow:
/weberror
App1.domain.com/
error.html
images/
image.jpg
style.css
App2.domain.com/
error.html
Images/
Image.jpg
Style.css
I receive the error.html in my browser, but the problem is any image or CSS
files linked to and referred from the error.html are not being evaluated and
returned.
Any help or advice would be appreciated. I am fairly new to Apache, and
mod_write. Config and logs are below:
<VirtualHost A.B.C.D:6443>
ServerName intgerror.domain com
ServerAlias intgsfms.domain.com
Include conf-intgerror-1/extra/httpd-ssl.conf
SSLEngine On
RewriteCond expr "! %{HTTP_REFERER} -strmatch '*://%{HTTP_HOST}/*'"
RewriteRule ^(.*)$ "%{DOCUMENT_ROOT}/weberror/%{HTTP_HOST}/error.html"
RewriteCond expr "%{HTTP_REFERER} -strmatch '*://%{HTTP_HOST}/*'"
RewriteRule %{REQUEST_URI}
"%{DOCUMENT_ROOT}/weberror/%{HTTP_HOST}/%{REQUEST_URI}"
</VirtualHost>
