Nginx configuration for hybrid-web-application to work with prerender.io service - open to bidding

Hello! I'm searching an expert to configure our nginx server. For our start-up [login to view URL] we built a Single Page Application based on backbone.js. The app is responsible for the main part of our webservice. In addition we use Wordpress to serve other content (imprint, team page etc.), because wordpress is easier to maintain. I got a hybrid version with both applications (single page and wordpress) working (running on [login to view URL]). The remaining problem is the configuration for prerender.io. A kind of middleware to make that kind of websites indexable for search engine bots. The prerender settings ([login to view URL]) are also correct on our server, because for testing reasons I made the app accesable under a seperate domain ([login to view URL]). With this "single installation" within nginx, all requests from bots were correctly forwarded to the prerender-service. But as mentioned the "hybrid-version" is not working correctly. I have some presumptions there as well, but couldn't find a complete solution. After I've investigated your profile, I'm quite confident that you could help us out with that problem! Best Christofer
