    Best practice usage usage of Umbraco Forms on load balanced environment

    Hi there, I was just wondering what's the best way to use Umbraco Forms when you're running your site on in a load balanced environment.

    Since the form definitions are stored as json in the filesystem, would we need to set up replication between servers on these files or is there some functionality included which caters for this?

    That's correct, you'll need to setup replication of the folder /App_Plugins/UmbracoForms/Data since that contains forms/workflows/datasources/prevaluesources

    What about files uploaded through a FileUpload field on your form? Will these files always get stored on the filesystem of the master instance or will this vary depending on which environment the user is on when they submit the form?

    Hi Tim, we have implemented the replication of the folder /App_Plugins/UmbracoForms/Data. Also we can see the changes we made to the forms json file are available on all the servers. The issue is we are not seeing the changes in the front end, we can only see the changes in the front end where admin is hosted.

    To see the changes we have to recycle the APP POOL in all the servers.

    I am seeing the same issue. The files are the same size and datestamp on both servers but only viewing the master site shows the changes.

    We solved this issue by disabling the Umbraco Forms caching in memory by editing the UmbracoForms.config file in the App_Plugins/UmbracoForms folder.

    <setting key="DisableFormCaching" value="True" />

    We had the same issues that Dan and Pankaj described.

    We run Donut caching and don't use Forms heavily so this worked for us.

    I have tried changing the DisableFormCaching setting but it makes no difference.

    Thanks Søren, setting <setting key="DisableFormCaching" value="True" /> worked for me too.
