0f081398cf0eef8cc7c66a535d450110a92dc8aefielding** URL Rewriting Module
0f081398cf0eef8cc7c66a535d450110a92dc8aefielding** This module uses a rule-based rewriting engine (based on a
0f081398cf0eef8cc7c66a535d450110a92dc8aefielding** regular-expression parser) to rewrite requested URLs on the fly.
0f081398cf0eef8cc7c66a535d450110a92dc8aefielding** It supports an unlimited number of additional rule conditions (which can
0f081398cf0eef8cc7c66a535d450110a92dc8aefielding** operate on a lot of variables, even on HTTP headers) for granular
0f081398cf0eef8cc7c66a535d450110a92dc8aefielding** matching and even external database lookups (either via plain text
0f081398cf0eef8cc7c66a535d450110a92dc8aefielding** tables, DBM hash files or even external processes) for advanced URL
0f081398cf0eef8cc7c66a535d450110a92dc8aefielding** substitution.
0f081398cf0eef8cc7c66a535d450110a92dc8aefielding** It operates on the full URLs (including the PATH_INFO part) both in
0f081398cf0eef8cc7c66a535d450110a92dc8aefielding** per-server context (httpd.conf) and per-dir context (.htaccess) and even
0f081398cf0eef8cc7c66a535d450110a92dc8aefielding** can generate QUERY_STRING parts on result. The rewriting result finally
0f081398cf0eef8cc7c66a535d450110a92dc8aefielding** can lead to internal subprocessing, external request redirection or even
0f081398cf0eef8cc7c66a535d450110a92dc8aefielding** to internal proxy throughput.
