When should same policies be added under both vcl_recv and vcl_fetch?
caching,reverse-proxy,varnish,varnish-vcl
I really cannot see why there should be any case where this is useful. You create hit-for-pass objects when the VCL has no idea that the resulting response cannot be caches. If the VCL can figure our that the response should not be cached you should just "pass" and be...

Transparent reverse proxying using org.restlet.routing.Redirector
java,http-headers,reverse-proxy,restlet,restlet-2.0
Thanks to Arjohn (see related discussion in Restlet mailing list) the solution was found: We've updated from restlet 2.1.4 to 2.2.0 now and to our surprise this fixed the Redirector problems. In fact, Redirector works perfectly out-of-the-box, including the digest authentication. No subclassing required. So probably this was a bug...

java,https,spring-security,reverse-proxy
If your site is HTTPS and you're running Apache Tomcat behind another system that's handling TLS termination, you can tell Tomcat to "pretend" that it's handling the TLS termination. This makes request.isSecure() return true; To do so, you need to add secure="true" to your Connector config in server.xml. https://tomcat.apache.org/tomcat-7.0-doc/config/http.html See...

What's difference between static and non-static resources?

In this case, a static resource refers to one that is not generated with code on the fly, meaning that its contents won't change from request to request. Images, JavaScript, CSS, etc., are all candidates for this. Basically, you set a large cache time for these resources, and your Nginx...

Reverse Proxy: Why response dispatch is not a bottleneck?

Apache ProxyPassReverse not rewriting Location header properly

Turns out I had improperly diagnosed this. The backend webserver (in this case, it happened to be rails) was actually specifying the http URL explicitly.
