I wrote a custom payment plugin to work with a french bank.
The bank API gives me a complete html string including a client redirection, that I send to the browser with this code :
string html = GetHtmlFormWithClientRedirect(commandLineParams.ToString());
HttpContext.Current.Response.Write(html);
HttpContext.Current.Response.End();
This solution does not work when we try to use OnePageCheckout, probably because of ajax. Does anybody already know a solution to solve this?
Thanks for your help,
Nicolas
