HQi has a redirect manager tool called Redirection. you can create and manage redirects quickly and easily without needing technical knowledge. 

There is full support for regular expressions so you can create redirect patterns to match any number of URLs. You can match query parameters and even pass them through to the target URL.

What you need to do is to login to HQi, select Redirection from Settings (on left panel navigation).
Then click "New Redirection".

Fill the Source URL input fields as the original URL/broken link, choose type of mapping URL, then fill the "Target URL" with the designated URL where the users will be redirected to (you may set this up to go to other website with adding full domain URL with its http/https) and choose the type of redirect you want to set this redirect as; permanent, temporary or 404, then save this. 

Once this has been set up, you can test this by typing the URL in the browser and click enter, when it has been set up correctly the browser will redirect you to the designated page URL where it has been set up in the redirection module.
