Ajax not working with this .htaccess

Question

Im developing a CMS with PHP and MVC. I have the follow htaccess:

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

So i have a dispatcher to go to diferents views depends of the permalink on the url.

My problem is that im trying to use ajax for a Login and few things more and cant make it works.

Is there any expception in .htaccess to make this work or i only can put more exceptions on dispatcher to load the .php in ajax?

Anyone can help me?

Thanks in advance.

EDIT:

$.post
(
    "../ajax/login.php",
    {
    u:Base64.encode(user),
    p:Base64.encode(password),
},
    function(data)
    {

    },
    "json"
);

I tried with:

"../ajax/login.php"

PATH+VIEW+THEME+"/ajax/login.php"

My folder structure is:

view
    themes
        standar
            ajax
                login.php
            js
                ajaxInteractions.js
            index.phtml

As stated in the comments, you need to check your path or just use your absolute path like this:

$.post
(
    "/view/themes/standar/ajax/login.php",
    {
    u:Base64.encode(user),
    p:Base64.encode(password),
},
    function(data)
    {

    },
    "json"
);

And one more thing; it is not always best practice to spread out the code like this ( it's good for PHP and plain JS calls ). For these types of calls, try to keep it more concentrated:

$.post( "/view/themes/standar/ajax/login.php", {
    u:Base64.encode(user),
    p:Base64.encode(password),
}, function(data) {
    /** do your stuff **/
}, "json" );
