you should also add a unit test for this

Thanks for the feedback, I committed the changes.

@fabpot could you review it ?

My comments:

 * `ServerBag` represents what we have in the `$_SERVER` global variables. As such, the code should be moved to the `getHeaders()` method instead like the other tweaks we do for the HTTP headers.

 * A comment must be added explaining why this is needed and the configuration the user must have to make it work (then remove the Github URLs).

 * The code should only be executed when `PHP_AUTH_USER` is not available (to not have any overhead when not needed).

A quick note on that .htaccess/apache configuration required, if adding to the Symfony SE htaccess file, then it will need to look like this:

```
<IfModule mod_rewrite.c>
    RewriteEngine On

    RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]

    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteRule ^(.*)$ app.php [QSA,L]
</IfModule>
```

NOTE: No **,L** in the Authorization Rewrite as in the original example - it prevents the front controller rewrite from happening

@kepten you were faster than me applying @fabpot's comments :) nevertheless part of the bug hunt day I also modified the ServerBag class and tested them on a productive LAMP hosting server using Apache and FastCGI

ok, so is my PR is useless or should I still fix problems?

---------------------------------------------------------------------------

by towards at 2012-04-20T16:20:26Z

your PR is fine for sure and I don't want to interfere, just wanted to mention that part of the bug hunt day of Symfony I had a go at this PR as an "exercise" but just saw later on that you already fixed the problem, so you can ignore my pushes

I have been working with @towards: your PR is useful, please implement his comments and squash your PR.
