How to redirect to Custom page from Page-initialization-script

Correct me if I'm wrong, but I had to deal with this before. The problem is: Error Requests never arrive at the page init code, they are generated and handled earlier and thus we can't handle them in page init!

You are also out of luck with the custom redirect Admin Feature (go to /t5/bizapps/bizappspage/tab/community%3Aadmin%3Asystem%3Aseo%3Aseo-redirects-settings in your community for that), at least if you want to redirect an arbitrary (non /t5/...) URL to somewhere else, e.g. /some_inexistent_page as a source URL will not be accepted...

Depending on how users "arrive" at the error page, e.g. through a link on your community, you might be able to intercept the link click with JavaScript and redirect from there, if that is not the case you might want to file a support case and ask if they can add that custom redirect directly to the Server config (Apache .htaccess or something)...but in your case it might be even trickier, as you don't want ALL users to be redirected, but just the ones without permission... Maybe a bit more details on what exactly you are dealing with would help craft a solution?

Hi duahire 

Please try this in Page Init - 

<#if http.request.url == "PERMISSION DENIED PAGE URL" >
  ${http.response.setRedirectUrl('CUSTOM PAGE URL')}
</#if>

Here's the Khoros documentation on the topic:
