How to redirect to a different Page on Site after submitting Form?

This is not supported in Appian. The only work around is to enable chaining in process and show the user an interface with a link to click.

Not even back to home page?

Thanks for response

The paradigm is always the same - when you run a process you are always returned to the place at which you initiated the process. 

What is your use case for starting a process in, say, a Record's Summary page and being returned to, say, the Record List...or even the home page of a Site? Why do you NOT want to be returned to the same place you started? Wouldn't the User Experience be confusing if you couldn't be sure of where you'd end up at after the process completed?

The record would have the information they just submitted so that they can view or see if there were any mistakes and edit it with a related action, whereas it refreshing onto the same page, sometimes they don't need to submit another form

As others noted, standard functionality is to return to where you were when the process began.  For this reason, I'll sometimes display a confirmation form within the same edit process via chain from the Edit form, with navigation options such as below.  Note when the users click the Home Page link, the task for the process will remain in their queue so I typically implement something like a 15-30 minute orphan timer.

I'm curious now Chris...what are your use cases for navigating to a different place from where you initiated a process? Human-System dialogue best practice is that "You ask the system to do something, it tells you it's done it" which is why I presume returning you to the place you left from gives you more opportunity to see the results of the process you just ran than by going elsewhere. For example; you're in a Customer Record. You run a process called "Update Customer Details". You change some details in a form and submit them. You're then returned to the Summary page where you can see your changes have been applied.

I think it was probably the way my process start(or start location) on this page, which was why I didn't want to come back to it.
