Answers.Body: <p>I got this working. I refactored my logic to use craft's <code>{{ redirectInput(urlParam) }}</code> instead of writing out my redirect param

Body: <p>I'm stuck on something and need some advice. I have a frontend login form where I need to dynamically change the redirect input value with JS when it changes. The page has instantsearch in place and I am trying to get the most current URL when a user interacts with the facets. I have a &quot;save your search&quot; setup in place but I have to have the user signed in to do this. I want them to be able to log in with my login form, and then return to the same URL. No matter what I have tried I cannot get Craft to validate the hashed return URL. Currently, I have JS in place that grabs the current URL, encodes it, and passes it as a param to a non-cached route via Ajax that renders a template where I am using the Craft filter <code>|hash</code> on the URL param, and parsing it out, then using that to update the form redirect param. However, it still won't pass validation in Craft and renders a 400 each time.</p>
