Re[2]: [users@httpd] Cookie-Based Rewrite

[Alan Little <da...@holotech.net>]

Thank you. Unfortunately, this is on a shared hosting server, and I
don't have access to the config files, nor the re-write log (if there
is one).

I figured out after I posted my question that I needed to exclude the
/demo/ directory, since that's where this is. I tried the regex you
suggested -- it makes more sense. But I still get the error. If I add
the RewriteCond for REQUEST_URI, I no longer get the error, but no
rewrite, either.

I must say, most of what I do with mod_rewrite is MSMD. I don't really
understand how it works, except in the most general terms. It would be
great if there was something that explained what exactly mod_rewrite
does, step by step, but all the tutorials I've been able to find are
really just recipes for doing various things, without really
explaining what's going on.

From what I understand, the rule as you wrote it goes:

> RewriteCond %{REQUEST_URI} !^/demo/

"If REQUEST_URI does not begin with /demo/"

> RewriteCond %{HTTP_COOKIE} phn_demo=([^;]+)

"...and HTTP_COOKIE contains 'phn_demo=' followed by a value"

> RewriteRule ^(.*) /%1/$1 [L]

"...rewrite the request to point to directory %1 (the value from
RewriteCond) below this directory, followed by whatever's left of
the URI."

Isn't that correct? It seems pretty straightforward to me, but for
some reason doesn't work.
