If you’re like me, you don’t like cluttering your main folder with unnecessary files. This is why I hate that some browsers are still looking for ‘favicon.ico’ in the main folder even when you indicate in <head> that’s not where the agent should be looking…
Here is a way to eliminate those PITA 404’s from your error logs… Continue reading
Just a quick snippet showing how to force the HTTPS protocol (SSL) and the “www” sub-domain…
RewriteEngine On
RewriteCond %{SERVER_PORT} 80 [OR]
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule ^(.*)$ https://www.mydomain.com/$1 [R=301,L]
There are other ways to achieve the same result, but I find this method is clean and requires the least amount of overhead to incorporate.
#Initialize mod_rewrite
RewriteEngine On
RewriteBase /
#Force "www" subdomain
RewriteCond %{HTTP_HOST} !^www\.
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L]
#Re-route forbidden urls
RewriteCond %{REQUEST_URI} ^(system|application).* [OR]
RewriteRule ^(.*)$ index.php?/$1 [L]
#Re-route urls if file/directory does not exist
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/$1 [L]
Another simple one.
The following code checks to see if the request is for a real directory or file and reroutes the request to “/myscript.php” if not.
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ myscript.php?/$1 [L]
</IfModule>
Take note of the the excamation point (it means “not”). To do the opposite (reroute valid directory/file requests through a script) just change the rewrite conditions (RewriteCond) to…
Short and sweet.
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\.
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L]
</IfModule>
And if you want to remove the “www” portion, just change the condition (RewriteCond) and rule (RewriteRule)…
You may ask “Why should I do this?” and the asnwers are simple. It promotes linking uniformity and ensures you don’t end up being negatively affected by having “duplicate content” across (sub)domains in search engine indexes.
I recently had the need to redirect one query string to another query string. The reason for this was we created a new item in our Zen Cart software that took the place of 3 other items. To make sure the search engines and our visitors reached the new product instead of the old ones, the following code was used to redirect them accordingly.
