Dear all,at our institution, we would like to provide additional landing pages via our handle server. I.e., a kind of proxy server application that runs on the handle server outside of the institutions network, and has access to certain services behind the firewall and can gather information/static pages from them.
We already have a basic PHP implementation that I wrote before it was clear that we would use the handle server for this task. Moreover, no-one in our team is too familiar with Java (apart from little projects back in university). So we were wondering whether it was possible to use the PHP application together with the handle.net software.
My first idea was to run both applications behind another web server (like nginx) but it turned out this isn't trivial due to encryption, authentication and the handle server using both TCP and UDP. So I abandoned the idea.
Since Jetty offers a FastCGI proxy library, and the handle manual explicitly says that the embedded Jetty can be further configured, I thought it should be possible to embed our PHP application this way. I dropped a simple PHP script (attachment) into /var/www/html and, guided by error messages and the Jetty manual, created a jetty.xml config file (attachment). I also added Jetty's fcgi-server.jar and jetty-proxy.jar v9.4.15 to the lib/servletContainer directory. Using this configuration, the server starts up just fine. However, accessing / results in HTTP/404 and /php-test/info.php results in HTTP/400, telling me the handle could not be resolved. So it seems some of the endpoints/servlets/handlers (I'm not sure about the Jetty terminology here) were overwritten while others were not. Please find attached the access and error logs. (Note: I ran the server locally on port 8443; IP is redacted.) I would be grateful if someone could help me get this up and running. I tried Stack Overflow already as this feels more like a general Jetty question that is not specific to handle.net. However, in typical Stack Overflow fashion, the only response I received was someone telling me off for still using Jetty 9 which is EOL. 😄
Finally, there's of course the option to implement our solution in Java. Though I'm not sure whether this solves the problem.
Thank you in advance and have a great week!
