I want to be able to create custom redirects that mask a long URL with meta tags behind a short URL. e.g. I want a custom url such as: pages.marketo.com/oil-webinar-partner
This ensures that, for example, partners and vendors, cannot edit/change our tracking tags, and makes sure the URL is short enough to fit in their system.
Third-party URL shortners aren't acceptable because I don't want to be reliant on another company that may go away, change TOU, or start inserting ads or something else in between the short URL and the full URL.
The Admin->Landing Pages->Rules function does not support this, as confirmed by Marketo customer support.
although I can't actually find this option on my own instance I did come across this article while looking for the ability to send multiple URLs to a single page that might be useful. https://community.marketo.com/MarketoArticle?id=kA050000000LNK3CAO
You can use any hostname you want, but you can't *also* use that exact hostname for another purpose*. So www.example.com can point to Marketo, then home.example.com can point to your website.
(Unless your IT staff understands and is equipped to route all of your requests through a reverse proxy -- infrequently, if ever, done.)
