referencing environment variables in mod_rewrite directives

[Wolli]

Hi,
in rewrite-rules I can adress $_SERVER-Variables by %{'VARNAME'}.
How can I adress $_ENV-variables?

They do hide it in the docs, don’t they? It’s
%{ENV:variable}
where “variable” is, as you would expect, the name of the variable.

this is documented here:
