Odd Mod_Rewrite Behaviour

Question

I've had a look at a few mod_rewrite questions here but nothing they have suggested has worked to date.

I have the below rules:

Options +FollowSymlinks RewriteEngine On RewriteBase / RewriteCond %{HTTPS} off RewriteRule ^(.*)$ https://%{HTTP_HOST}/$1 [L,R=301] RewriteCond %{HTTP_HOST} !^www\. RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [L,R=301] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^([^-]*)/$ ?action=$1 [L] ## General Pages RewriteRule ^privacy-policy/$ ?action=privacy-policy [L] RewriteRule ^terms-conditions/$ ?action=terms-conditions [L] RewriteRule ^about/$ ?action=about [L] RewriteRule ^contact-us/$ ?action=contact-us [L] RewriteRule ^sitemap.xml$ ?action=sitemap [L] ## Blog Pages RewriteRule ^blog/$ ?action=blog [L] RewriteRule ^blog/([a-zA-Z0-9-]+)/$ ?action=blog&category=$1 [L] RewriteRule ^blog/([a-zA-Z0-9-]+)/([0-9]+)-([a-zA-Z0-9-]+)/$ ?action=blog&category=$1&id=$2&title=$3 [L]

The first blog rule works fine and the third blog rule works fine.

The second blog rule isn't working correctly, lets say I have the below URL:

/blog/general/

The second blog rule is returning blog/general as the value for categorywhich is incorrect, it should only be returning general as the value for category.

This issue only occurs on my production environment, it doesn't happen on my local dev environment.

I'm really stumped on this one, any suggestions greatly appreciated.

@anubhava, no other rules relating to blogs, there are about another 10/15 rules for other areas of the website. The issue doesn't occur on my local dev environment, only on my production environment, very odd. — llanato

@anubhava blog isn't a directory no, it's a virtual path, there is only on htaccess file on the server. — llanato

Try reordering your rules and merge SSL with www rule to avoid multiple redirects (bad for SEO and client experience):

Options +FollowSymlinks RewriteEngine On RewriteBase / RewriteCond %{HTTP_HOST} !^www\. [NC,OR] RewriteCond %{HTTPS} off RewriteCond %{HTTP_HOST} ^(?:www\.)?(.+)$ [NC] RewriteRule ^ https://www.%1%{REQUEST_URI} [R=301,L,NE] ## General Pages RewriteRule ^privacy-policy/$ ?action=privacy-policy [L] RewriteRule ^terms-conditions/$ ?action=terms-conditions [L] RewriteRule ^about/$ ?action=about [L] RewriteRule ^contact-us/$ ?action=contact-us [L] RewriteRule ^sitemap.xml$ ?action=sitemap [L] ## Blog Pages RewriteRule ^blog/$ ?action=blog [L,QSA] RewriteRule ^blog/([a-zA-Z0-9-]+)/$ ?action=blog&category=$1 [L,QSA] RewriteRule ^blog/([a-zA-Z0-9-]+)/([0-9]+)-([a-zA-Z0-9-]+)/$ ?action=blog&category=$1&id=$2&title=$3 [L,QSA] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^([^-]*)/$ ?action=$1 [L,QSA]

Working perfectly now, I suppose it was the general catch all rewrite for the action parameter causing the issue.
