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
