How rewrite target URL in reverse proxy developed with Apache http-core-4.3.3
java,apache,reverse-proxy,apache-httpcomponents
HttpRequest and HttpResponse objects are very cheap. When implementing a proxy with HttpCore you should always be making a copy of incoming messages instead of passing the same object for several reasons: URI rewriting being one handling of so called hop-by-hop headers being another protocol upgrade / downgrade when for...
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...

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...
Apache ProxyPassReverse not rewriting Location header properly
apache,mod-rewrite,reverse-proxy,mod-proxy,mod-ssl
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. This is because it was using the incoming request parameters to build its redirection URL. So, since ProxyPreserveHost was enabled, it was getting the host...
