htaccess redirect double check

[wesg]

Hello Gurus,
I've been searching WebmasterWorld Forums for the solution, and have hammered out code that does 90% of what I want it to do.

My goal is to have all user agents iPod and iPhone (I'm making my site mobile) be redirected to sub.domain.com from domain.com. So far I have succeeded in having both user agents be redirected to sub.domain.com/index.php. I want to drop the index.php and have pages redirected to their respective subdomain page.

For example, http://www.example.com/contact/ should redirect to http://sub.example.com/contact/

Here is what I have so far, and I hope that the geniuses on this forum can help me figure out the rest.

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{HTTP_USER_AGENT} (.*iPod.*¦.*iPhone.*) [NC]
RewriteRule ^(.*) http://sub.example.com/$1? [R=301,L]
</IfModule>

This is the .htaccess file in my main domain, by the way.

In what way is it failing for URLs that you do want to redirect, and for URLs that you do not want to redirect?

You do not need the .* patterns in the USER_AGENT test.

You can use iPod¦iPhone or even iP(od¦hone) just fine.

By failing I mean it's not detecting the extra address on the script.

That means that a request for http://www.example.com/contact redirects to http://sub.example.com/index.php instead of http://sub.example.com/contact.

Flush your browser cache, because it should work just fine.

You also need to test with inputs of both www.domain.com/contact and domain.com/contact too.

[wesg]

Flushed the cache, still no dice. It must be something simple wrong.

[jdMorgan]

Something simple? Not necessarily... You've got an internal rewrite to index.php being applied first, and then the code posted here is "exposing" that rewrite. You'll need to move the code posted here so that it is applied *before* the code that does that internal rewrite to the script. That might be easy or it might be impossible, depending on how your hosting is set up and whether you're using a "control panel" or a host-managed script installer.

I found something interesting. I am using pretty permalinks on my wordpress blog, and I found this in the subdomain htaccess. Perhaps this is the problem?

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

[g1smd]

Yes it is.

You need to get the redirect in, before the rewrite.

[wesg]

I think I know what I have to do now. I have to add a condition to the subdomain that says only do the rewrite like that if the user is coming from my main domain. How could I do that?

[g1smd]

Changing the order will do what you want to do.

[wesg]

I see your point. However, the htaccess files I"m talking about are two separate files. One is in the main domain which handles the redirect, and the second is in the subdomain, which makes the wordpress permalinks pretty. Is there a way to do it in one file?
