MVC multiple sites issue

?Have you seen the article on Multisite environment in MVC yet? I hope it helps. However, we do not recommend hosting multiple sites in one instance and one code base - if something goes wrong, then all sites are down.

All sites going down is an acceptable result in this case, and keeping infrastructure and code updates to a minimum is preferred. If I want to continue down this path, how do I get Kentico to correctly resolve the current site? Basic functionality like .OnCurrentSite() does not work as soon as I enter a second site.

Could you please describe or provide screen shots what are the admin domain and presentation URLs set for each site in Kentico admin? Then, how is configured your routing to work with these domains and routes?

I can't share the exact domains for confidential reasons, but they both follow this format:

Site domain name: admin.dev.xxxx.com

Presentation URL: http://www.xxxx.com

Where "xxxx" is different between the two sites. Does MVC routing impact how .OnCurrentSite() or CMS.SiteProvider.SiteContext.CurrentSite work? Is there something the MVC code supposed to manually identify the site based on domain before calls are made to the Kentico APIs?

If you have different domains set for each site I do not see a problem - especially if the Presentation URL is set correctly. What is your routing like? How does your MVC app distinguish between the domains? When in admin, do you have the right admin domain in the browser's URL? Isn't it possible you have a different tab with the other admin domain opened? Otherwise, as a workaround you could use .OnSite(< sitename >) in your code

Thanks for the replies Juraj. I'm not sure I'm following the MVC routing question. Most of my routes look something like this:

route = routes.MapRoute(
    name: "Home",
    url: "{culture}",
    defaults: new { culture = defaultCulture.Name, controller = "Home", action = "Index" },
    constraints: new { culture = new SiteCultureConstraint() }
);
route.RouteHandler = new MultiCultureMvcRouteHandler(defaultCulture);

My app doesn't currently distinguish between the domains because all of the routes will be identical between the sites, it's just different content. I assumed Kentico would see the domain and match the site via the presentation URL and filter content accordingly within .OnCurrentSite(). Is that not the case?

I tried it by using the sample Dancing Goat MVC project - I have created a new site, basically export and import of existing site, just set different domains in Kentico admin. Both live sites in the IIS are pointing to the same MVC project and it is working fine. Could you please check the sample Dancing Goat project to see what is different in your case? Or, try reproducing the issue using this project so I can reproduce it as well and take further look what is going on.
