完全失去與的.htaccess

Question

我有我的託管以下文件夾結構（它是一個共享的一個）

public_html 
| 
| 
|--- website (contains CodeIgniter application) 
|--- otherapp (another CodeIgniter application) 
|--- moreapp (yet another web application) 

什麼我想要做的是，當過用戶鍵入我的域名（http://example.com）它應該加載「網站」文件夾內的內容。

當用戶輸入http://otherapp.example.com時，它應該打開什麼index.php駐留在'otherapp'文件夾中。

首先我試圖此（和在根文件夾保存它[的public_html]）：

Redirect /index.php http://example.com/otherapp/index.php and it pretty much screwed the URL and links. 

然後我試圖此（來自的Joomla htaccess的蠻力拷貝粘貼）：

## 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] 

在otherapps文件夾（這是codeigniter的應用程序，我有這個特定的.htaccess） 其中： 1.擺脫index.php結尾蹤跡 2.通過做一些緩存加快網頁加載

<IfModule mod_rewrite.c> 
    RewriteEngine On 
    RewriteBase/

    #Removes access to the system folder by users. 
    #Additionally this will allow you to create a System.php controller, 
    #previously this would not have been possible. 
    #'system' can be replaced if you have renamed your system folder. 
    RewriteCond %{REQUEST_URI} ^system.* 
    RewriteRule ^(.*)$ /index.php?/$1 [L] 

    #When your application folder isn't in the system folder 
    #This snippet prevents user access to the application folder 
    #Submitted by: Fabdrol 
    #Rename 'application' to your applications folder name. 
    RewriteCond %{REQUEST_URI} ^application.* 
    RewriteRule ^(.*)$ /index.php?/$1 [L] 

    #Checks to see if the user is attempting to access a valid file, 
    #such as an image or css document, if this isn't true it sends the

我現在面臨的問題是一些鏈接沒有正確重定向。我不知道如何解釋這個問題（我認爲這太亂了）。

將這個規則在根目錄的.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]
