This is my mod_proxy config:
<IfModule mod_proxy.c>
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
ProxyPass /manage/ http://localhost:9000/manage/
ProxyPassReverse /manage/ http://localhost:9000/manage/
</IfModule>
I find that whenever the other website I have on port 9000 doesn't respond correctly, I get sustained 503 errors - that persist even after the website is fixed. In other words, the 503 response seems to be cached.
How can I disable it? I don't think I have enabled caching myself, perhaps this is the default.
