I'm running into various problems trying to add custom ErrorDocuments to my server.
I'm using proxy balancer to share the load between two instances of Zope and some simple rewrite rules to map my domain to the local zope instances. I'm pretty sure Zope isn't the problem, but have mentioned it to explain what the balancer redirects to.
I've tried a number of suggestions, but the 'closest' I can get is included below and results in the error:
"Firefox has detected that the server is redirecting the request for this address in a way that will never complete."
Other variations result in:
"The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.
Additionally, a 503 Service Temporarily Unavailable error was encountered while trying to use an ErrorDocument to handle the request."
If I include a simple
ErrorDocument 503 Hello
It renders fine.
What am I doing wrong? I'm worried that it may be something to do with the balancer/rewrite getting 'in the way' of the custom errors? Or that my DocumentRoot is incorrectly set?
The rest of this configuration runs fine without the custom errors.
