what is wrong with this .htaccess and Yii urlManager settings? - .htaccess

Question

I have a yii website under a sub directory e.g
http://localhost/~username/maindirectory/yiiapp/
My htaccess file:
DirectoryIndex index.php index.html index.htm
Options +FollowSymLinks
IndexIgnore */*
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteBase /yiiapp
# if a directory or a file exists, use it directly
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
# otherwise forward it to index.php
RewriteRule . index.php
</IfModule>
protected/config/main.php
...
'urlManager'=>array(
'urlFormat'=>'path',
'showScriptName'=>false,
....
The issue:
let say I accesss :
step one: http://localhost/~username/maindirectory/yiiapp/
step two: click any link on home page (default yii app) let say About Us page
step three: http://localhost/~username/maindirectory/yiiapp/site/page?view=about
step four : click on any on the link (let say same page)
url will look like : http://localhost/yiiapp/site/page?view=about
so : all links are accessible as : http://localhost/yiiapp/.... , instead of removing index.php from link the while string b/w localhost and base directory is removed .
I tried this already and need the same sort of url on localhost , obviously without using sub domains
please help me fix this .

Answer 1

Partial answer:
The problem is that you are redirecting to an absolute URL on the same domain.
The URL probably looks like /yiiapp/site/page?view=about. However that leads to http://localhost/yiiapp/site/page?view=about. You must prepend the website directory relative to the domain (not sure if I expressed properly).
For example, the URL in the a href tag should look like /~username/maindirectory/yiiapp/site/page?view=about so you must prepend the /~username/maindirectory part from somewhere.

Have your tried:
'urlManager'=>array(
....
'baseUrl' => '/~username/maindirectory/yiiapp',
....

Answer 3

so RewriteBase /~username/maindir/yiiapp , in .htaccess fixed the issue , not the
'baseUrl' => '/~username/maindirectory/yiiapp' thing in config/main.php
Here is the full .htaccess file:
DirectoryIndex index.php index.html index.htm
Options +FollowSymLinks
IndexIgnore */*
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteBase /~username/maindir/yiiapp
# if a directory or a file exists, use it directly
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
# otherwise forward it to index.php
RewriteRule . index.php
</IfModule>
