= FAQ =
== Multiple mongrel instances? ==
Never run only a single mongrel instance, Rails is not thread safe. 90% of the time you need to run TWO in order to get any level of acceptable performance.

== proxy_redirect? ==
I noticed on some apps that redirections break. It seems it was stripping the proxy_pass from the redirection url:

<geshi lang="nginx">
upstream beast { ... }
proxy_pass http://beast;
</geshi>

In my rails production log I see "Redirected to http://beast.caboo.se/login". However, livehttpheaders only sees '.caboo.se/login'. Adding the proxy_redirect false; above fixes it.
