[users@httpd] some principal questions concerning mod_rewrite
Hi,
i'd like to use mod_rewrite, but i have some problems in understanding it.
- "RewriteRule pattern subtitution [flags]":
Is substitution always an URL ? Also in cases when pattern is matched against the filesystem path ?
Is a RewriteRule always applied to an URL, meaning the URL will change depending on the substitution ?
- What means (in directory context) "... after removing the prefix that lead the server to the current RewriteRule" ? Which prefix is removed ? That of the URL or that of the filesystem path ?
- "per-directory Rewrites": "When using the rewrite engine in .htaccess files the per-directory prefix (...) is automatically removed for the RewriteRule pattern matching and automatically added after any relative (not starting with a slash or protocol name) substitution encounters the end of a rule set." Does this not apply to directory context, only to .htaccess ? Again: what is removed ? The prefix of an URL or that of a filesystem path ? And where is it added ? In an URL or in a filesystem path ?
Thanks for any clarifying.
Bernd
