Need help about redirect of apache!
 

Hi ,all
How can apache do this:

When access http://domain1/index.php , apache redirect to http://domain2/index.php ?
But when access http://domain1/index.php?something, not redicect?

only use .htaccess.

Thanks.

But when access http://domain1/index.php?something, not redicect?

this cannot be done..

Have you provided the complete path to the page after which you trying to redirect?
It seems you are not providing the complete path.

When access http://domain1/index.php (only this url), redirect to http://domain2/index.php

but when access http://domain1/index.php?something , not redirect.

here something stands for sth like 'key=a'.

In my .htaccess:
RewriteEngine on
RedirectMatch 301 ^/index.php$ http://domain2/index.php

but when I access 'http://domain1/index.php?key=a', it redirects to

http://domain2/index.php too..

You have to use mod_rewrite in order to be able to redirect such URLs and not Redirect
Regards

I do enabled mod_rewrite.

I use your code, but when I access http://localhost/index.php?key=1
,it goes to domain2 again.

what I want is when access and only access 'http://localhost/index.php', it redirect to 'http://domain2/index.php', any other urls like 'http://localhost/index.php?key=1' ,do not redirect.

Thanks a lot, I've tried all day, almost freak...

Or you can do it with PHP by adding something like this to the top of your index.php file on domain1:

You didn't say anything about localhost ;)
Anyway, you have to add a RewriteCond for localhost:
Note that Redirect (uses mod_alias) is different than mod_rewrite
