best way to ease CI into a large site

[eluser]skattabrain[/eluser]
what about this ... it seems to work

system direcory on the root ... and my $config['index_page'] is set to ""

.htaccess file ...

Code:

RewriteEngine on
RewriteRule ^welcome/(.*)$ my-temporary-ci-default-page.php/$1 [L]

so i this seems to be behaving and working. any ideas on this? i guess what i'm looking for is to prevent any "gotchas" down the road.
