Completely lost with .htaccess - php

Question

i have the following folder structure on my hosting (it is a shared one)
public_html
|
|
|--- website (contains CodeIgniter application)
|--- otherapp (another CodeIgniter application)
|--- moreapp (yet another web application)
What i want to do is that when ever a user type my domain (http://example.com) it should loads the content within the 'website' folder.
While a user type http://otherapp.example.com it should open what ever index.php reside within the 'otherapp' folder.
First i tried this (and saved it in the root folder[public_html]):
Redirect /index.php http://example.com/otherapp/index.php and it pretty much screwed the URL and links.
Then i tried this (a brute copy paste from Joomla htaccess):
## Can be commented out if causes errors, see notes above.
Options +FollowSymLinks
## Mod_rewrite in use.
RewriteEngine On
# Block out any script trying to base64_encode data within the URL.
RewriteCond %{QUERY_STRING} base64_encode[^(]*\([^)]*\) [OR]
# Block out any script that includes a <script> tag in URL.
RewriteCond %{QUERY_STRING} (<|%3C)([^s]*s)+cript.*(>|%3E) [NC,OR]
# Block out any script trying to set a PHP GLOBALS variable via URL.
RewriteCond %{QUERY_STRING} GLOBALS(=|\[|\%[0-9A-Z]{0,2}) [OR]
# Block out any script trying to modify a _REQUEST variable via URL.
RewriteCond %{QUERY_STRING} _REQUEST(=|\[|\%[0-9A-Z]{0,2})
# Return 403 Forbidden header and show the content of the root homepage
RewriteRule .* index.php [F]
##
# Uncomment following line if your webserver's URL
# is not directly related to physical file paths.
# Update Your Joomla! Directory (just / for root).
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
# If the requested path and file is not /index.php and the request
# has not already been internally rewritten to the index.php script
RewriteCond %{REQUEST_URI} !^/index\.php
# and the request is for something within the component folder,
# or for the site root, or for an extensionless URL, or the
# requested URL ends with one of the listed extensions
RewriteCond %{REQUEST_URI} /component/|(/[^.]*|\.(php|html?|feed|pdf|vcf|raw))$ [NC]
# and the requested path and file doesn't directly match a physical file
RewriteCond %{REQUEST_FILENAME} !-f
# and the requested path and file doesn't directly match a physical folder
RewriteCond %{REQUEST_FILENAME} !-d
# internally rewrite the request to the index.php script
RewriteRule .* index.php [L]
Within otherapps folder (which is the codeigniter application i have this specific .htaccess)
which:
1. To get rid of index.php ending trail
2. Speed up web page load by doing some caching
<IfModule mod_rewrite.c>

RewriteRule ^(.*)$ /index.php?/$1 [L]

The problem that i am facing at the moment is that some links are not redirected properly. I am not sure how to explain the problem (i think it is too random).

Answer 1

Place this rule in root .htaccess:
RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} ^(www\.)?example\.com$ [NC]
RewriteRule ^((?!website/).*)$ website/$1 [NC,L]
RewriteCond %{HTTP_HOST} ^otherapp\.example\.com$ [NC]
RewriteRule ^((?!otherapp/).*)$ otherapp/$1 [NC,L]
