Thank you page redirect

Explains how to configure the thank you page redirect.



Optimizely Forms is only supported by MVC-based websites and HTML5-compliant browsers.

After a visitor submits a form, you can redirect them to a Thank you page using the Display page after submission field. You can have several forms go to the same Thank you page, so the following elements (in the redirect URL) let you know which form the visitor submitted using the DefaultAppendExtraInfoToRedirection class.

  • FormGuid – Unique ID of the FormContainerBlock. Use this ID to look up the form instance.
  • FormLanguage – Language of the container page (where FormContainerBlock is dropped).
  • FormSubmissionId – Unique ID of the submission. Use this ID to look up the recent submission (which drives a visitor to the Thank you page).

Forms.Core provides the IAppendExtraInfoToRedirection interface, and lets you customize the Thank you page. You should:

  1. Implement the interface.
  2. Make an InitializationModule, and use Dependency Injection to replace the default implementation.

A third-party developer can alter this behavior by implementing IAppendExtraInfoToRedirection, and using StructureMap in InitializationModule (DemoInitializationModule.cs) to replace the default implementation:

public void Initialize(InitializationEngine context) {
  _serviceConfigurationContext.Container.Configure(c => {
    c.For < IAppendExtraInfoToRedirection > ().Use(new AppendInfoToRedirection());
