drupal_http_request with proxy

Question

I'm working on proxy based machine where I've configured my proxy settings at settings.php and its working fine.

When I'm trying to access a URL the data is getting displayed perfectly, for instance, https://maps.googleapis.com/maps/api/geocode/json?address=California but when I'm doing the same thing at my devel/php

$maps_url = 'https://maps.googleapis.com/maps/api/geocode/json?address=California';
$maps_json = drupal_http_request($maps_url);
dsm($maps_json);

it's returning me this:

I've confirmed 2 settings in my php.ini:

1. allow_url_fopen
2. allow_url_include

Where else should I look so that this issue will get fixed?

Answer 1

Found this module cURL HTTP Request via this thread and it worked like charm. The issue was with HTTPS hence the HTTP proxy module wasn't able to help me on this.
