RewriteRule / RewriteCond help when two "keywords" show in the one query string - apache

Question

Currently I have this in my .htaccess file:
<IfModule mod_rewrite.c>
Options -MultiViews
RewriteEngine On
RewriteBase /forum/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule \.(jpeg|jpg|gif|png)$ /forum/public/404.php [NC,L]
RewriteCond %{QUERY_STRING} (?:^|&)app=core(?:&|$) [NC]
RewriteCond %{QUERY_STRING} (?:^|&)section=register(?:&|$) [NC]
RewriteRule ^index\.php$ http://www.mysite.com/register.php? [NC,L,R=302]
RewriteCond %{QUERY_STRING} (?:^|&)app=core(?:&|$) [NC]
RewriteCond %{QUERY_STRING} (?:^|&)section=login(?:&|$) [NC]
RewriteRule ^index\.php$ http://www.mysite.com/login.php? [NC,L,R=302]
RewriteCond %{QUERY_STRING} (?:^|&)app=core(?:&|$) [NC]
RewriteCond %{QUERY_STRING} (?:^|&)section=lostpass(?:&|$) [NC]
RewriteRule ^index\.php$ http://www.mysite.com/retrieve_password.php? [NC,L,R=302]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /forum/index.php [L]
</IfModule>
The one I need help with is this one:
RewriteCond %{QUERY_STRING} (?:^|&)app=core(?:&|$) [NC]
RewriteCond %{QUERY_STRING} (?:^|&)section=login(?:&|$) [NC]
RewriteRule ^index\.php$ http://www.mysite.com/login.php? [NC,L,R=302]
Currently this will redirect something like:
http://www.mysite.com/forum/index.php?app=core&module=global&section=login
The &module=global isn't required so as I'm sure you can tell it only looks for the app & section parameters.
However the problem is, it also redirects the logout link I want to redirect somewhere else as it also contains app=core & &section=login.
Here is an example:
http://www.mysite.com/forum/index.php?app=coree&module=global&section=login&do=logout&k=xxxxxxxxxxxxxxxxxxx
So basically the login should still redirect as above unless it has &do=logout in the query string; in that case I want to redirect it somewhere else.
How can I go about doing this?

Answer 1

Change your rule to:
RewriteCond %{QUERY_STRING} (?:^|&)app=core(?:&|$) [NC]
RewriteCond %{QUERY_STRING} (?:^|&)section=login(?:&|$) [NC]
RewriteCond %{QUERY_STRING} !(?:^|&)do=logout(?:&|$) [NC]
RewriteRule ^index\.php$ http://www.mysite.com/login.php? [NC,L,R=302]
Here RewriteCond %{QUERY_STRING} !(?:^|&)do=logout(?:&|$) [NC] will skip redirect if &do=logout is present in the query string.
EDIT: As per comments:
RewriteCond %{QUERY_STRING} (?:^|&)app=core(?:&|$) [NC]
RewriteCond %{QUERY_STRING} (?:^|&)section=login(?:&|$) [NC]
RewriteCond %{QUERY_STRING} (?:^|&)do=logout(?:&|$) [NC]
RewriteRule ^index\.php$ http://www.mysite.com/logout.php? [NC,L,R=302]
