[thelist] Re: Apache mod_rewrite and PHP SID

[Tony Light]

Problem solved - thanks to some digging in the Apache docs.

Answer: Many server variables are available to you when creating
RewriteRules for mod_rewrite.
The query string is one of them.
So to ensure that any query string that may be present is passed on in the
rewritten url, append it as follows:

RewriteRule ^/([0-9])/?$
/play/modrewrite/echo.php?id=$1&%{QUERY_STRING}

If I was concerned about the content of %{QUERY_STRING}, then I could check
it in a RewriteCond immediately before the RewriteRule.
e.g.
RewriteCond %{QUERY_STRING}             ^(|PHPSESSID=([0-9a-f]){32})$

... would mean that the RewriteRule would only take place if the query
string did not exist at all, or was exactly of the format "PHPSESSID=" plus
a 32 char session id.

Hope this helps someone.

Thanks to all who gave their time to reply.

Cheers,
    Tony.
