What about using PHP imports?
I was wondering if the documenation backend is written in PHP. If it is, then you could actually make references to other pages without having to redirect the to other links. Using PHP imports, one can display content from other pages directly inisde an element on the page that the is currently viewing. I use this feature extensively throughout my own website to get around some convoluted details of CSS. For example my header and footer are separate pages, but I import them. One could forseeably break up the documentation pages into separate pages that act as containers and then display them wherever they want them. In my case what this did for me, is that it reduced the issue of typographical errors. It created consistency across my pages and I didn’t have to re-write content or code.
