Using mod_rewrite to handle various content issues

Is this correct? (redirecting /index.php --> /)

Postby Sarge » Fri Feb 01, 2008 5:01 am

I'm using this to redirect domain.com to www.domain.com and /index.php to /:

Code: Select all
# Redirect domain.com/* --> www.domain.com/*
RewriteCond %{HTTP_HOST} ^domain\.com$ [NC]
RewriteRule ^(.*)$ http://www.domain.com/$1 [R=301,L]

# Redirect /index.php --> /
RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /index\.php\ [NC]
RewriteRule ^index\.php$ http://www.domain.com/ [R=301,L]


It's working fine as far as I can tell. But I'd like to know, is it correct or is there room for improvement?

They're fine. To be slightly more efficient you can put them the other way round as when removing index.php it adds www in the same rule.

Hmmm. I noticed today that redirection of index.php wasn't working and I don't know why. Strange, it was working fine before. I switched recently to Apache 2.2.8, could it be the issue?

domain.com gets redirected to www.domain.com just fine. The index.php part is what doesn't work.

domain.com/index.php gets redirected to www.domain.com/index.php and www.domain.com/index.php stays the same (surprise, surprise...) I switched the rules around, still with the same result.

I'm now using this and it seems to work (feels faster too):
RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /.*index\.php\ HTTP/
RewriteRule ^(.*)index\.php$ http://www.domain.com/$1 [R=301,L]

The code for www is still the same.

Do you think there could be any possible issues?

Is it working now? Is the mod_rewrite in a .htaccess file?
Code: Select all
Options +FollowSymLinks

RewriteEngine On

# Redirect /index.php --> /
RewriteCond %{THE_REQUEST} ^[a-z]{3,9}\ (/[^\ ]+)?/index\.php(\?.*)?\ [NC]
RewriteRule ^(.+/)?index\.php$ http://www.domain.com/ [R=301,L]

# Redirect domain.com/* --> www.domain.com/*
RewriteCond %{HTTP_HOST} ^domain\.com$ [NC]
RewriteRule ^(.*)$ http://www.domain.com/$1 [R=301,L]

Of course the rewrite is in .htaccess.

Your last rewrite works only if I replace [NC] with HTTP/ and [a-z] wasn't working. I also have subdirectories. So I used this:

Code: Select all
# Redirect /index.php --> /
RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ (/[^\ ]+)?/index\.php(\?.*)?\ HTTP/
RewriteRule ^(.+/)?index\.php$ http://www.domain.com/$1 [R=301,L]


The only problem is that the AJAX-based post preview in my SMF forum doesn't work (the contents is empty).

This works fine:
Code: Select all
# Redirect /index.php --> /
RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /.*index\.php\ HTTP/
RewriteRule ^(.*)index\.php$ http://www.domain.com/$1 [R=301,L]


With either of the above, index.php gets redirected, but index.php? doesn't. And neither works with [NC], should it be a problem?

Thanks for your help so far!

Try
Code: Select all
Options +FollowSymLinks

RewriteEngine On

# Redirect /index.php --> /
RewriteCond %{THE_REQUEST} \ /(.+/)?index\.php(\?.*)?\  [NC]
RewriteRule ^(.+/)?index\.php$ http://www.domain.com/%1 [NC,R=301,L]

The above doesn't work with AJAX post previews either.

Also, index.php? is rewritten as ? which is still not good enough.

Also, only index.php and index.php? should be rewritten, not index.php?*.

does your AJAX request URLs with index.php in it?
Do you have URLs like .../index.php?query=string?

Try
Code: Select all
Options +FollowSymLinks

RewriteEngine On

RewriteCond %{THE_REQUEST} \ /(.+/)?index\.php\?\  [NC]
RewriteRule ^(.+/)?index\.php$ http://www.domain.com/%1? [NC,R=301,L]

RewriteCond %{THE_REQUEST} \ /(.+/)?index\.php(\?.+)?\  [NC]
RewriteRule ^(.+/)?index\.php$ http://www.domain.com/%1 [NC,R=301,L]
