Apache Reference: mod_cern_meta

mod_cern_meta - Creation of Arbitrary HTTP Headers (CERN-style)
Since Apache 1.1, src/modules/standard/mod_cern_meta.c
Andrew Wilson (1996)

mod_cern_meta is a backward-compatible module that provides approximately the same functionality as mod_headers, albeit in a somewhat different way. Instead of being configured through Apache directives, the headers are placed inside a dedicated meta-file.

Directives:

MetaFiles	MetaDir
MetaSuffix
