I had explored that method already, sadly (as you know) “alias” is
as an absolute path meaning I can’t use this block of config within
multiple virtual hosts which I include; - would have to re-write this
block of config for each Virtual host modifying the alias path prefix.
And since alias man page explicitly states that $document_root can’t be
used it’s not possible to complete this config in a reusable way. (e.g.
alias $document_root/path/to/$1/$2; would be perfect).
Alas, I think what I have (storing the captures in temp vars) is the
real solution thus far.
Unless the penny hasn’t dropped in my head?
