Composer behind proxy not working for symfony proj

In my workplace network we have to use a proxy. I want to use Composer a to download some package dependencies for my Symfony2 projects. It does not work even after declaring the environment variable with the proxy information. I noticed that we are also unable to revolve any external name using the DNS of the company. And I think that one is the main problem that does not alow us to download with composer. The truth is that I can not change any thing on those servers or policies of the company. Do you think that I can do something that can let me resolve those names or access those resources to install the dependencies? this is the error:

The "http://thirds.packagist.dev/packages.json" file could not be downloaded (HTTP/1.0 503 Service Unavailable)

http://thirds.packagist.dev could not be fully loaded, package information was loaded from the local cache and may be out of date

Also I tried to declared the ip of packagist.org on my etc hosts... and then i notices that the DNS that is used is not the one of my localhost:

root@zeus:/home/abel/Documents/http/team# php composer.phar update

I once faced the same issue, and setting the proxy in my terminal solved the problem.

If you're using Windows, enter these commands :

set HTTP_PROXY=http://user:password@proxy.domain.com:port
set HTTPS_PROXY=http://user:password@proxy.domain.com:port

In Unix system, the command is export instead of set.

Then you can run composer update command.

If you still have problems, it might be git that needs the proxy configuration too. In your %HOMEPATH%\.gitconfig, add the following :

[http]
    proxy = http://user:password@proxy.domain.com:port

EDIT:

Since you've added the results of composer diag, the problem seems to be that your proxy doesn't handle the request_fulluri flag for HTTPS requests.

You can disable this option by setting the environment variable HTTPS_PROXY_REQUEST_FULLURI like this (Unix system) :
