Hello, Adam, Elliot -- The application is question right now is a pure javascript application, IIPMooViewer, that is designed to work with Djatoka. One of my colleagues is modifying that application for our own environment, and she is currently getting some information from the javascript location property.
My question was slightly a more philosophical one... many web applications out there in the world do not rely entirely on relative URLs, which can make them tricky to integrate with a disseminator. Also, there's the overhead of passing requests to an application through a disseminator -- I'd rather avoid having every request to a web application go through Fedora, if there's no need beyond the first request. The use case I'm thinking of is where the disseminator simply becomes a gateway to a representation of the digital object that is handled elsewhere: Fedora's role, in this case, is to provide that entry point, hand off the resource to the external application, then step out of the picture. One workaround we're trying out this morning: have the disseminator point to an external URL managed by Apache; Apache then grabs the bits of the request it needs using mod_rewrite, builds a new URL, and does a RedirectPermanent to the new location. Slightly more elegant, in that we don't need to maintain a separate web service just to do a redirect. -- Scott [email protected] wrote: > Scott-- > > Can you say a little more about this backend service in particular?
