    Loadbalancing issues in 7.3-beta3

    Hi

    Currently we are running a Umbraco 7.3-beta3 in azure.

    We have the following setup :

    • 1 VM that is used for content editing
    • 1 Web app at the moment for front end (umbraco backend access is restrictred using IIS rewrites)

    When I publish something in the content editing instance (VM) these changes are not always visible on the front end (Web app)

    When I look in the umbracoServer table I see both instances as active. Also the last notified date get's updated after changes for both instances.

    But when I log in through FTP on the web app I see that the file in /App_Data/TEMP/DistCache/ doesn't have the latest id found in the umbracoCacheInstruction table

    When the web app restarts this get's updated all content changes are visible.

    Am I missing some config settings or code to make this work?

    It seems to work flawless on our dev environments. When one developer publishes something on his machine, all other registered instances are updated.

    I just discoverd that the lastNotifiedDate doesn't get update when doing a publish for the web app. This only happens after the app has been restarted.

    I did some more testing. Only seems to occur when a node doesn't have a domain assigned. But only in the Azure environment. If i publish a node that has a domain assigned all changes are visible after that.

    Still digging :-)

    After some more digging I discoverd that the syncing is done when you make a request to the load balanced instance.

    But we have some custom Url providers and virtual node handlers in place and it doesn't seem to sync when you call a virtual url.

    So did some more digging.

    It seems when you do a request to the website the Sync method on the Umbraco.Core.Sync.DatabaseServerMessenger is called.

    However when we call a page with a virtual node this method doesn't seem to be called.

    From logs when calling a normal page

    Just updated the issue with the following information.

    It seems that virtual routes are not seen as routeable in Umbraco.

    I just attached debugger and have found the following result.

    In https://github.com/umbraco/Umbraco-CMS/blob/dev-v7/src/Umbraco.Web/UmbracoModule.cs the method EnsureUmbracoRoutablePage is called for each (non client side request)

    In this method EnsureDocumentRequest is false for a virtual node.

    This because the call to the method IsReservedPathOrUrl in https://github.com/umbraco/Umbraco-CMS/blob/dev-v7/src/Umbraco.Core/Configuration/GlobalSettings.cs

    In this method a route is found for the virtual node and Umbraco sees this as reserverd path.

    Because of this the outcome of EnsureUmbracoRoutablePage is EnsureRoutableOutcome.NotDocumentRequest.

    In the method UmbracoModule_RouteAttempt in https://github.com/umbraco/Umbraco-CMS/blob/dev-v7/src/Umbraco.Web/BatchedDatabaseServerMessenger.cs the sync method is only called for backend request the outcome is EnsureRoutableOutcome.NotDocumentRequest.
