Sitecore.Web.WebUtil.Redirect not working with Ajax call

Question

I have an Sitecore app (9.0.2) MVC application, in which I send to the Controller a FormCollection object, with an Ajax call (because I create dynamically tabs with in View).

On the Controller, I have a redirect to a payment service:

WebUtil.Redirect(new RealExService().RedirectPost(postData, Sitecore.Configuration.Settings.GetSetting("realexurl","https://pay.realexpayments.com/pay")).AbsoluteUri);
(...)
return View("~/Views/Complete.cshtml", viewModel);

The issue is that when the redirect happens, Request Method automatically changes to OPTIONS and thus I get a status code of 403 and the payment form is not shown.

I have switched the POST request from AJAX call to MVC form submit and it works as expected. (with the price of losing dynamic content on the View)

Any ideas?

Thank you.

Answer 1

I have fixed the issue by replacing

WebUtil.Redirect(new RealExService().RedirectPost(postData, Sitecore.Configuration.Settings.GetSetting("realexurl","https://pay.realexpayments.com/pay")).AbsoluteUri);
(...)
return View("~/Views/Complete.cshtml", viewModel);

with

return Content(new RealExService().RedirectPost(postData, Sitecore.Configuration.Settings.GetSetting("realexurl", "https://pay.realexpayments.com/pay")).AbsoluteUri);

and in the Ajax call:

success: function (response, textStatus, jQxhr) 
{
   window.location.href = response;
}
