doc: clarify run-plugin argument is fixed at load time - #13429
Merged
Conversation
The run-plugin action's plugin-argument is parsed once when the
rule loads, like a remap.config argument, and is never
re-evaluated per request, so variable interpolation (e.g.
%{HEADER:bar}) does not work there.

Pull request overview
This PR clarifies the run-plugin directive behavior in the header_rewrite admin guide by documenting that the "<plugin-argument> ..." string is parsed once at rule load/reload time (similar to remap.config) and is not re-evaluated per request, so variable interpolation does not apply.
Changes:
- Add a documentation note under
run-pluginexplaining that<plugin-argument>is fixed at load/reload time. - Explicitly state that per-request variable interpolation (e.g.
%{HEADER:bar}) does not work inrun-pluginarguments.
