How can I redirect to another file but keep index.php access

I will try to explain this in the simplest terms I can think to avoid confusing anyone.

I have a site that I've moved to a sub开发者_运维技巧directory, it will go away soon but for needs access. In the root I have a wordpress install with an index.php file.

Basically for the time being I need this:

User types www.site.com they get taken to www.site.com/comingsoon.php User types www.site.com/index.php they get taken to that actual URL (no redirect)

This is the only line I have in my .HTACCESS:

DirectoryIndex comingsoon.php

but that doesn't seem to work as if they go www.site.com/index.php (by typing that explicitly) they still get redirected to the coming soon page.

I can't rename the index.php from wordpress.

Any help is appreciated.

Try this code in your .htaccess file:

Options +FollowSymlinks -MultiViews
RewriteEngine on
RewriteRule ^/?$ /comingsoon.php [L]

This will only internally redirect www.site.com or www.site.com/ to /comingsoon.php. But if you type www.site.com/index.php it should not do any redirection.
