I am using Gravity Forms to post (confirmation redirect) to Salesforce, send out a notification, and return to my retURL in the redirect. Everything works like a charm in Firefox. In IE the redirect does not appear to be working at all (nothing in Salesforce, nothing in debug, does NOT return to retURL value - just refreshes to same page form is on.
One other thing that could be a factor (I don't know). My setup is not ideal. Running WP on IIS6 and there are some other things "not working." Couldn't get the GF Salesforce addon to work OR the salesforce WP addon. However, redirect has worked (at least in FF) since day one so I headed that route. Just checked in IE (compatibility and non-c modes) and the redirect does not work. Any ideas? The redirect code is (zeroed out the actual ID:
