copied!<p>A reverse proxy setup (e.g. nginx forwarding HTTP requests to Starman) has the following advantages:</p> <ul> <li><p>things are a bit easier to debug, since you can easily hit directly the backend server;</p></li> <li><p>if you need to scale your backend server, you can easily use something like pound/haproxy between the frontend (static-serving) HTTP and your backends (Zope is often deployed like that);</p></li> <li><p>it can be a nice sidekick if you are also using some kind of outward-facing, caching, reverse proxy (like Varnish or Squid) since it allows to bypass it very easily.</p></li> </ul> <p>However, it has the following downsides:</p> <ul> <li><p>the backend server has to figure out the real originating IP, since all it will see is the frontend server address (generally localhost); there is almost an easy way to find out the client IP address in the HTTP headers, but that's something extra to figure out;</p></li> <li><p>the backend server does not generally know the orignal "Host:" HTTP header, and therefore, cannot automatically generated an absolute URL to a local resource; Zope addresses this with special URLs to embed the original protocol, host and port in the request to the backend, but it's something you don't have to do with FastCGI/Plack/...;</p></li> <li><p>the frontend cannot automatically spawn backend processes, like it could do with FastCGI for instance.</p></li> </ul> <p>Pick your favourites pros/cons and make your choice, I guess ;-)</p>
