Resolve by expression (ap_expr)
Resolving variables by expression could be an alternative for resolution by executing a process for simple conditionals or copying of variables.
The functionality would overlap with SetEnvIfExpr
of the mod_setenvif module and RewriteRule
(when is this expr evaluated?) of the mod_rewrite module, but would be consistent with ResolveByProcess
and would offer further functionality such as evaluation at different stages of the request lifecycle.
